Examples
Code Editor (JavaScript)
print('Error function of -10', ee.Number(-10).erf()); // -1
print('Error function of -0.001', ee.Number(-0.001).erf()); // -0.001128378
print('Error function of 0', ee.Number(0).erf()); // 0
print('Error function of 0.001', ee.Number(0.001).erf()); // 0.001128378
print('Error function of 10', ee.Number(10).erf()); // 1
Python setup
See the
Python Environment page for information on the Python API and using
geemap for interactive development.

import geemap.core as geemap
Colab (Python)
print('Error function of -10:', ee.Number(-10).erf().getInfo()) # -1

print('Error function of 0:', ee.Number(0).erf().getInfo()) # 0
# 0.001128378
print('Error function of 0.001:', ee.Number(0.001).erf().getInfo())
print('Error function of 10:', ee.Number(10).erf().getInfo()) # 1
