उदाहरण

कोड एडिटर (JavaScript)

// Cast a number to unsigned 32-bit integer: [0, 4294967295].
var number = ee.Number(100);
print('Number:', number);

var uint32Number = number.uint32();
print('Number cast to uint32:', uint32Number);


/**
 * 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.uint32();
print('Floating point value cast to uint32:', floatToUint32);

// A number greater than uint32 range max cast to uint32 becomes uint32 range max.
