Subtracts the second value from the first.
| Usage | Returns | Number.subtract(right) | Number |
| Argument | Type | Details | this: left | Number | The left-hand value. |
right | Number | The right-hand value. |
Examples
Code Editor (JavaScript)
print('5 - 10', ee.Number(5).subtract(10)); // -5
print('10 - 5', ee.Number(10).subtract(5)); // 5
print('5 - 10.2', ee.Number(5).subtract(10.2)); // -5.199999999
print('5 - -10.2', ee.Number(5).subtract(-10.2)); // 15.2
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
Colab (Python)
print('5 - 10:', ee.Number(5).subtract(10).getInfo()) # -5
print('10 - 5:', ee.Number(10).subtract(5).getInfo()) # 5
print('5 - 10.2:', ee.Number(5).subtract(10.2).getInfo()) # -5.199999999
print('5 - -10.2:', ee.Number(5).subtract(-10.2).getInfo()) # 15.2
