math – mathematical functions
This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: math.
The math
module provides some basic mathematical functions for working with floating-point numbers.
Note: On the pyboard, floating-point numbers have 32-bit precision.
Availability: not available on WiPy. Floating point support required for this module.
