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

Mathematical functions.
This module provides an interface to a number of mathematical functions.
A collection of mathematical functions that return floats. Arguments are numbers.
Returns the error function of X
, where:
erf(X) = 2/sqrt(pi)*integral from 0 to X of exp(-t*t) dt.
erfc(X)
returns 1.0
- erf(X)
, computed by methods that avoid cancellation for large X
.
A useful number.
As these are the C library, the same limitations apply.
