ee.Number.long
Casts the input value to a signed 64-bit integer.
Usage | Returns |
---|
Number.long() | Number |
Argument | Type | Details |
---|
this: input | Number | The input value. |
Examples
// Declare an ee.Number.
var number = ee.Number(100);
print('ee.Number:', number);
// Cast a number to signed 64-bit integer.
var longNumber = number.long();
print('ee.Number cast to long:', longNumber);
/**
* Casting numbers to long 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 long loses decimal precision.
var float = ee.Number(1.7);
print('Floating point value:', float);
var floatToLong = float.long();
print('Floating point value cast to long:', floatToLong);

It takes a Number as input and returns a Number. Casting a floating-point number to long results in the loss of decimal precision. Numbers outside the range and precision of a 64-bit integer may be modified during the cast. Examples demonstrate casting a regular number and a floating number into long using JavaScript and Python.\n"]]
