ee.Number.signum
Computes the signum function (sign) of the input; 0 if the input is 0, 1 if the input is greater than 0, -1 if the input is less than 0.
| Usage | Returns |
|---|
Number.signum() | Number |
| Argument | Type | Details |
|---|
this: input | Number | The input value. |
Examples
print('Sign of -5', ee.Number(-5).signum()); // -1
print('Sign of 0', ee.Number(0).signum()); // 0
print('Sign of 5', ee.Number(5).signum()); // 1
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.
import ee
import geemap.core as geemap
print('Sign of -5:', ee.Number(-5).signum().getInfo()) # -1
print('Sign of 0:', ee.Number(0).signum().getInfo()) # 0
print('Sign of 5:', ee.Number(5).signum().getInfo()) # 1
