उदाहरण

कोड एडिटर (JavaScript)

// Cast a number to signed 8-bit integer: [-128, 127].
var number = ee.Number(100);
print('Number:', number);

var int8Number = number.toInt8();
print('Number cast to int8:', int8Number);


/**
 * Casting numbers to int8 that are outside of its range and precision can
 * modify the resulting value, note the behavior of the following scenarios.
 */

// A floating point number cast to int8 loses decimal precision.
var float = ee.Number(1.7);
print('Floating point value:', float);

var floatToInt8 = float.toInt8();
print('Floating point value cast to int8:', floatToInt8);

// A number greater than int8 range max cast to int8 becomes int8 range max.
var INT8_MAX = 127;
var outOfRangeHi = ee.Number(INT8_MAX + 12345);
print('Greater than int8 max:', outOfRangeHi);

var outOfRangeHiToInt8 = outOfRangeHi.toInt8();
print('Greater than int8 max cast to int8 becomes int8 max:', outOfRangeHiToInt8);

// A number greater than int8 range min cast to int8 becomes int8 range min.
var INT8_MIN = -128;
var outOfRangeLo = ee.Number(INT8_MIN - 12345);
print('Less than int8 min:', outOfRangeLo);

var outOfRangeLoToInt8 = outOfRangeLo.toInt8();
print('Less than int8 min cast to int8 becomes int8 min:', outOfRangeLoToInt8);
