उदाहरण

कोड एडिटर (JavaScript)

// Cast a number to unsigned 16-bit integer: [0, 65535].
var number = ee.Number(100);
print('Number:', number);

var uint16Number = number.toUint16();
print('Number cast to uint16:', uint16Number);

 * Casting numbers to uint16 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 uint16 loses decimal precision.
var float = ee.Number(1.7);
print('Floating point value:', float);

var floatToUint16 = float.toUint16();

// A number greater than uint16 range max cast to uint16 becomes uint16 range max.
