-:mod:`math` -- mathematical functions
-=====================================
-
-.. module:: math
-   :synopsis: mathematical functions
-
-|see_cpython_module| :mod:`python: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.
-
-Functions
----------

-   Return the inverse hyperbolic tangent of ``x``.
-
-.. function:: ceil(x)
-
-   Return an integer, being ``x`` rounded towards positive infinity.

-
-.. function:: erf(x)
-
-   Return the error function of ``x``.
-
-.. function:: erfc(x)
-
-   Return the complementary error function of ``x``.
-
-.. function:: exp(x)
-
-   Return the exponential of ``x``.
-
-.. function:: expm1(x)
-
