 * Casting numbers to int 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 int loses decimal precision.
var float = ee.Number(1.7);
print('Floating point value:', float);

var floatToInt = float.toInt();
print('Floating point value cast to int:', floatToInt);

// A number greater than int range max cast to int becomes int range max.
var INT_MAX = 2147483647;
var outOfRangeHi = ee.Number(INT_MAX + 12345);
print('Greater than int max:', outOfRangeHi);

var outOfRangeHiToInt = outOfRangeHi.toInt();
print('Greater than int max cast to int becomes int max:', outOfRangeHiToInt);

// A number greater than int range min cast to int becomes int range min.
var INT_MIN = -2147483648;
var outOfRangeLo = ee.Number(INT_MIN - 12345);
print('Less than int min:', outOfRangeLo);

var outOfRangeLoToInt = outOfRangeLo.toInt();
print('Less than int min cast to int becomes int min:', outOfRangeLoToInt);
