Mathematical Functions
This module provides an interface to a number of mathematical functions.
Note!
Not all functions are implemented on all platforms. In particular,
the erf/1
and erfc/1
functions are not implemented on Windows.
Functions
pi/0
A useful number.
sin/1
cos/1
tan/1
asin/1
acos/1
atan/1
atan2/2
sinh/1
cosh/1
tanh/1
asinh/1
acosh/1
atanh/1
exp/1
log/1
log10/1
pow/2
sqrt/1
A collection of math functions which return floats. Arguments are numbers.
erf/1
Returns the error function of
, where
erf(X) = 2/sqrt(pi)*integral from 0 to X of exp(-t*t) dt.
erfc/1
erfc(X)
returns 1.0 - erf(X)
, computed by
methods that avoid cancellation for large
.
Bugs
As these are the C library, the bugs are the same.
