 * Casting numbers to uint32 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 uint32 loses decimal precision.
var float = ee.Number(1.7);
print('Floating point value:', float);

var floatToUint32 = float.toUint32();
print('Floating point value cast to uint32:', floatToUint32);

// A number greater than uint32 range max cast to uint32 becomes uint32 range max.
var UINT32_MAX = 4294967295;
var outOfRangeHi = ee.Number(UINT32_MAX + 12345);
print('Greater than uint32 max:', outOfRangeHi);

var outOfRangeHiToUint32 = outOfRangeHi.toUint32();
print('Greater than uint32 max cast to uint32 becomes uint32 max:', outOfRangeHiToUint32);

// A number greater than uint32 range min cast to uint32 becomes uint32 range min.
var UINT32_MIN = 0;
var outOfRangeLo = ee.Number(UINT32_MIN - 12345);
print('Less than uint32 min:', outOfRangeLo);

var outOfRangeLoToUint32 = outOfRangeLo.toUint32();
