math Mathematical functions.

This module provides an interface to a number of mathematical functions.

Not all functions are provided on all platforms. In particular, the erf/1 and erfc/1 functions are not provided on Windows.

Diverse math functions.

A collection of mathematical functions that return floats. Arguments are numbers.

Error function.

Returns the error function of X, where:

erf(X) = 2/sqrt(pi)*integral from 0 to X of exp(-t*t) dt.

Another error function.

erfc(X) returns 1.0 - erf(X), computed by methods that avoid cancellation for large X.

Ratio of the circumference of a circle to its diameter.

Floating point approximation of mathematical constant pi.

Ratio of the circumference of a circle to its radius.

This constant is equivalent to a full turn when described in radians.

The same as 2 * pi().

Limitations

As these are the C library, the same limitations apply.
