# Float

public final class **Float** extends [Number](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Number.html)  
implements [Comparable](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Comparable.html)\<[Float](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html)\> The `Float` class wraps a value of primitive type
`float` in an object. An object of type
`Float` contains a single field whose type is
`float`.

In addition, this class provides several methods for converting a
`float` to a `String` and a
`String` to a `float`, as well as other
constants and methods useful when dealing with a
`float`.

represents the primitive `float` argument.

##### Parameters

| value | the value to be represented by the `Float`. |
|---|---|

#### public
**Float**
(double value)

Constructs a newly allocated `Float` object that
represents the argument converted to type `float`.

##### Parameters

|---|---|

##### See Also

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#valueOf(java.lang.String)`

## Public Methods

#### public byte
**byteValue**
()

Returns the value of this `Float` as a `byte` after
a narrowing primitive conversion.

##### Returns

- the `float` value represented by this object converted to type `byte`

#### public static int
**compare**
(float f1, float f2)

Compares the two specified `float` values. The sign
of the integer value returned is the same as that of the
integer that would be returned by the call:

```
    new Float(f1).compareTo(new Float(f2))
 
```

<br />

##### Parameters

| f1 | the first `float` to compare. |
| f2 | the second `float` to compare. |
|---|---|

##### Returns

- the value `0` if `f1` is numerically equal to `f2`; a value less than `0` if `f1` is numerically less than `f2`; and a value greater than `0` if `f1` is numerically greater than `f2`.

#### public int
**compareTo**
([Float](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html) anotherFloat)

Compares two `Float` objects numerically. There are
two ways in which comparisons performed by this method differ
from those performed by the Java language numerical comparison
operators (`<, <=, ==, >=, >`) when
applied to primitive `float` values:

- `Float.NaN` is considered by this method to be equal to itself and greater than all other `float` values (including `Float.POSITIVE_INFINITY`).
- `0.0f` is considered by this method to be greater than `-0.0f`.

This ensures that the *natural ordering* of `Float` objects imposed by this method is *consistent with equals*.

<br />

##### Parameters

| anotherFloat | the `Float` to be compared. |
|---|---|

##### Returns

- the value `0` if `anotherFloat` is numerically equal to this `Float`; a value less than `0` if this `Float` is numerically less than `anotherFloat`; and a value greater than `0` if this `Float` is numerically greater than `anotherFloat`.

##### See Also

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Comparable.html#compareTo(T)`

#### public double
**doubleValue**
()

Returns the value of this `Float` as a `double`
after a widening primitive conversion.

##### Returns

- the `float` value represented by this object converted to type `double`

#### public boolean
**equals**
([Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) obj)

Compares this object against the specified object. The result
is `true` if and only if the argument is not
`null` and is a `Float` object that
represents a `float` with the same value as the
`float` represented by this object. For this
purpose, two `float` values are considered to be the
same if and only if the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#floatToIntBits(float)`
returns the identical `int` value when applied to
each.

Note that in most cases, for two instances of class
`Float`, `f1` and `f2`, the value
of `f1.equals(f2)` is `true` if and only if

> ```
>    f1.floatValue() == f2.floatValue()
>  
> ```

also has the value `true`. However, there are two exceptions:

- If `f1` and `f2` both represent `Float.NaN`, then the `equals` method returns `true`, even though `Float.NaN==Float.NaN` has the value `false`.
- If `f1` represents `+0.0f` while `f2` represents `-0.0f`, or vice versa, the `equal` test has the value `false`, even though `0.0f==-0.0f` has the value `true`.

This definition allows hash tables to operate properly.

<br />

##### Parameters

| obj | the object to be compared |
|---|---|

##### Returns

- `true` if the objects are the same; `false` otherwise.

##### See Also

- `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#floatToIntBits(float)`

#### public static int
**floatToIntBits**
(float value)

Returns a representation of the specified floating-point value
according to the IEEE 754 floating-point "single format" bit
layout.

Bit 31 (the bit that is selected by the mask
`0x80000000`) represents the sign of the floating-point
number.
Bits 30-23 (the bits that are selected by the mask
`0x7f800000`) represent the exponent.
Bits 22-0 (the bits that are selected by the mask
`0x007fffff`) represent the significand (sometimes called
the mantissa) of the floating-point number.

If the argument is positive infinity, the result is
`0x7f800000`.

If the argument is negative infinity, the result is
`0xff800000`.

If the argument is NaN, the result is `0x7fc00000`.

In all cases, the result is an integer that, when given to the
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#intBitsToFloat(int)` method, will produce a floating-point
value the same as the argument to `floatToIntBits`
(except all NaN values are collapsed to a single
"canonical" NaN value).

##### Parameters

| value | a floating-point number. |
|---|---|

##### Returns

- the bits that represent the floating-point number.

#### public static int
**floatToRawIntBits**
(float value)

Returns a representation of the specified floating-point value
according to the IEEE 754 floating-point "single format" bit
layout, preserving Not-a-Number (NaN) values.

Bit 31 (the bit that is selected by the mask
`0x80000000`) represents the sign of the floating-point
number.
Bits 30-23 (the bits that are selected by the mask
`0x7f800000`) represent the exponent.
Bits 22-0 (the bits that are selected by the mask
`0x007fffff`) represent the significand (sometimes called
the mantissa) of the floating-point number.

If the argument is positive infinity, the result is
`0x7f800000`.

If the argument is negative infinity, the result is
`0xff800000`.

If the argument is NaN, the result is the integer representing
the actual NaN value. Unlike the `floatToIntBits`
method, `floatToRawIntBits` does not collapse all the
bit patterns encoding a NaN to a single "canonical"
NaN value.

In all cases, the result is an integer that, when given to the
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#intBitsToFloat(int)` method, will produce a
floating-point value the same as the argument to
`floatToRawIntBits`.

##### Parameters

| value | a floating-point number. |
|---|---|

##### Returns

- the bits that represent the floating-point number.

#### public float
**floatValue**
()

Returns the `float` value of this `Float` object.

##### Returns

- the `float` value represented by this object

#### public int
**hashCode**
()

Returns a hash code for this `Float` object. The
result is the integer bit representation, exactly as produced
by the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#floatToIntBits(float)`, of the primitive
`float` value represented by this `Float`
object.

##### Returns

- a hash code value for this object.

#### public static int
**hashCode**
(float value)

Returns a hash code for a `float` value; compatible with
`Float.hashCode()`.

##### Parameters

| value | the value to hash |
|---|---|

##### Returns

- a hash code value for a `float` value.

#### public static float
**intBitsToFloat**
(int bits)

Returns the `float` value corresponding to a given
bit representation.
The argument is considered to be a representation of a
floating-point value according to the IEEE 754 floating-point
"single format" bit layout.

If the argument is `0x7f800000`, the result is positive
infinity.

If the argument is `0xff800000`, the result is negative
infinity.

If the argument is any value in the range
`0x7f800001` through `0x7fffffff` or in
the range `0xff800001` through
`0xffffffff`, the result is a NaN. No IEEE 754
floating-point operation provided by Java can distinguish
between two NaN values of the same type with different bit
patterns. Distinct values of NaN are only distinguishable by
use of the `Float.floatToRawIntBits` method.

In all other cases, let *s*, *e*, and *m* be three
values that can be computed from the argument:

>     int s = ((bits >> 31) == 0) ? 1 : -1;
>      int e = ((bits >> 23) & 0xff);
>      int m = (e == 0) ?
>                      (bits & 0x7fffff) << 1 :
>                      (bits & 0x7fffff) | 0x800000;
>      
Then the floating-point result equals the value of the mathematical expression *s*·*m*·2^*e*-150^.

Note that this method may not be able to return a
`float` NaN with exactly same bit pattern as the
`int` argument. IEEE 754 distinguishes between two
kinds of NaNs, quiet NaNs and *signaling NaNs*. The
differences between the two kinds of NaN are generally not
visible in Java. Arithmetic operations on signaling NaNs turn
them into quiet NaNs with a different, but often similar, bit
pattern. However, on some processors merely copying a
signaling NaN also performs that conversion. In particular,
copying a signaling NaN to return it to the calling method may
perform this conversion. So `intBitsToFloat` may
not be able to return a `float` with a signaling NaN
bit pattern. Consequently, for some `int` values,
`floatToRawIntBits(intBitsToFloat(start))` may
*not* equal `start`. Moreover, which
particular bit patterns represent signaling NaNs is platform
dependent; although all NaN bit patterns, quiet or signaling,
must be in the NaN range identified above.

**toHexString**
(float f)

Returns a hexadecimal string representation of the

- If the argument is NaN, the result is the string "`NaN`".
- Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '`-`' (`'\u002D'`); if the sign is positive, no sign character appears in the result. As for the magnitude *m*:
  - If *m* is infinity, it is represented by the string `"Infinity"`; thus, positive infinity produces the result `"Infinity"` and negative infinity produces the result `"-Infinity"`.
  - If *m* is zero, it is represented by the string `"0x0.0p0"`; thus, negative zero produces the result `"-0x0.0p0"` and positive zero produces the result `"0x0.0p0"`.
  - If *m* is a `float` value with a normalized representation, substrings are used to represent the significand and exponent fields. The significand is represented by the characters `"0x1."` followed by a lowercase hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed unless all the digits are zero, in which case a single zero is used. Next, the exponent is represented by `"p"` followed by a decimal string of the unbiased exponent as if produced by a call to `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Integer.html#toString(int)` on the exponent value.
  - If *m* is a `float` value with a subnormal representation, the significand is represented by the characters `"0x0."` followed by a hexadecimal representation of the rest of the significand as a fraction. Trailing zeros in the hexadecimal representation are removed. Next, the exponent is represented by `"p-126"`. Note that there must be at least one nonzero digit in a subnormal significand.

| Floating-point Value | Hexadecimal String |
|---|---|
| `1.0` | `0x1.0p0` |
| `-1.0` | `-0x1.0p0` |
| `2.0` | `0x1.0p1` |
| `3.0` | `0x1.8p1` |
| `0.5` | `0x1.0p-1` |
| `0.25` | `0x1.0p-2` |
| `Float.MAX_VALUE` | `0x1.fffffep127` |
| `Minimum Normal Value` | `0x1.0p-126` |

#### public static [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**toString**
(float f)

Returns a string representation of the `float`
argument. All characters mentioned below are ASCII characters.

- If the argument is NaN, the result is the string "`NaN`".
- Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '`-`' (`'\u002D'`); if the sign is positive, no sign character appears in the result. As for the magnitude *m*:
  - If *m* is infinity, it is represented by the characters `"Infinity"`; thus, positive infinity produces the result `"Infinity"` and negative infinity produces the result `"-Infinity"`.
  - If *m* is zero, it is represented by the characters `"0.0"`; thus, negative zero produces the result `"-0.0"` and positive zero produces the result `"0.0"`.
  - If *m* is greater than or equal to 10^-3^ but less than 10^7^, then it is represented as the integer part of *m*, in decimal form with no leading zeroes, followed by '`.`' (`'\u002E'`), followed by one or more decimal digits representing the fractional part of *m*.
  - If *m* is less than 10^-3^ or greater than or equal to 10^7^, then it is represented in so-called "computerized scientific notation." Let *n* be the unique integer such that 10^*n*^≤ *m* \< 10^*n*+1^; then let *a* be the mathematically exact quotient of *m* and 10^*n*^ so that 1 ≤ *a* \< 10. The magnitude is then represented as the integer part of *a*, as a single decimal digit, followed by '`.`' (`'\u002E'`), followed by decimal digits representing the fractional part of *a*, followed by the letter '`E`' (`'\u0045'`), followed by a representation of *n* as a decimal integer, as produced by the method `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Integer.html#toString(int)`.

How many digits must be printed for the fractional part of *m* or *a*? There must be at least one digit to represent the fractional part, and beyond that as many, but only as many, more digits as are needed to uniquely distinguish the argument value from adjacent values of type `float`. That is, suppose that *x* is the exact mathematical value represented by the decimal representation produced by this method for a finite nonzero argument *f*. Then *f* must be the `float` value nearest to *x*; or, if two `float` values are equally close to *x*, then *f* must be one of them and the least significant bit of the significand of *f* must be `0`.

To create localized string representations of a floating-point
value, use subclasses of `https://developers.google.com/j2objc/javadoc/jre/reference/java/text/NumberFormat.html`.

##### Parameters

| f | the float to be converted. |
|---|---|

##### Returns

- a string representation of the argument.

#### public static [Float](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html)
**valueOf**
([String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html) s)

Returns a `Float` object holding the
`float` value represented by the argument string
`s`.

If `s` is `null`, then a
`NullPointerException` is thrown.

Leading and trailing whitespace characters in `s`
are ignored. Whitespace is removed as if by the `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html#trim()` method; that is, both ASCII space and control
characters are removed. The rest of `s` should
constitute a *FloatValue* as described by the lexical
syntax rules:

> *FloatValue:*
> :   *Sign~opt~* `NaN`
> :   *Sign~opt~* `Infinity`
> :   *Sign~opt~ FloatingPointLiteral*
> :   *Sign~opt~ HexFloatingPointLiteral*
> :   *SignedInteger*
>
> *HexFloatingPointLiteral*:
> :   *HexSignificand BinaryExponent FloatTypeSuffix~opt~*
>
> *HexSignificand:*
> :   *HexNumeral*
> :   *HexNumeral* `.`
> :   `0x` *HexDigits~opt~ *`.`* HexDigits*
> :   `0X`* HexDigits~opt~ *`.` *HexDigits*
>
> *BinaryExponent:*
> :   *BinaryExponentIndicator SignedInteger*
>
> *BinaryExponentIndicator:*
> :   `p`
> :   `P`
where *Sign*, *FloatingPointLiteral*, *HexNumeral*, *HexDigits*, *SignedInteger* and *FloatTypeSuffix* are as defined in the lexical structure sections of The Java™ Language Specification, except that underscores are not accepted between digits. If `s` does not have the form of a *FloatValue*, then a `NumberFormatException` is thrown. Otherwise, `s` is regarded as representing an exact decimal value in the usual "computerized scientific notation" or as an exact hexadecimal value; this exact numerical value is then conceptually converted to an "infinitely precise" binary value that is then rounded to type `float` by the usual round-to-nearest rule of IEEE 754 floating-point arithmetic, which includes preserving the sign of a zero value. Note that the round-to-nearest rule also implies overflow and underflow behaviour; if the exact value of `s` is large enough in magnitude (greater than or equal to (`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#MAX_VALUE` + `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Math.html#ulp(float)`/2), rounding to `float` will result in an infinity and if the exact value of `s` is small enough in magnitude (less than or equal to `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#MIN_VALUE`/2), rounding to float will result in a zero. Finally, after rounding a `Float` object representing this `float` value is returned.

To interpret localized string representations of a
floating-point value, use subclasses of `https://developers.google.com/j2objc/javadoc/jre/reference/java/text/NumberFormat.html`.

Note that trailing format specifiers, specifiers that
determine the type of a floating-point literal
(`1.0f` is a `float` value;
`1.0d` is a `double` value), do
*not* influence the results of this method. In other
words, the numerical value of the input string is converted
directly to the target floating-point type. In general, the
two-step sequence of conversions, string to `double`
followed by `double` to `float`, is
*not* equivalent to converting a string directly to
`float`. For example, if first converted to an
intermediate `double` and then to
`float`, the string  

`"1.00000017881393421514957253748434595763683319091796875001d"`  

results in the `float` value
`1.0000002f`; if the string is converted directly to
`float`, `1.0000001f` results.

To avoid calling this method on an invalid string and having
a `NumberFormatException` be thrown, the documentation
for `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Double.html#valueOf(double)` lists a regular
expression which can be used to screen the input.

##### Parameters

| s | the string to be parsed. |
|---|---|

##### Returns

- a `Float` object holding the value represented by the `String` argument.

##### Throws

| [NumberFormatException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NumberFormatException.html) | if the string does not contain a parsable number. |
|---|---|

#### public static [Float](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html)
**valueOf**
(float f)

Returns a `Float` instance representing the specified
`float` value.
If a new `Float` instance is not required, this method
should generally be used in preference to the constructor
`https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Float.html#Float(float)`, as this method is likely to yield
significantly better space and time performance by caching
frequently requested values.

##### Parameters

| f | a float value. |
|---|---|

##### Returns

- a `Float` instance representing `f`.
