MODULE SUMMARY
Mathematical Functions
DESCRIPTION
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.
EXPORTS
A useful number.
sin(X)
cos(X)
tan(X)
asin(X)
acos(X)
atan(X)
atan2(Y, X)
sinh(X)
cosh(X)
tanh(X)
asinh(X)
acosh(X)
atanh(X)
exp(X)
log(X)
log10(X)
pow(X, Y)
sqrt(X)
Types:
X = Y = number()
A collection of math functions which return floats. Arguments are numbers.
Types:
X = number()
Returns the error function of X, where
erf(X) = 2/sqrt(pi)*integral from 0 to X of exp(-t*t) dt.
Types:
X = number()
erfc(X) returns 1.0 - erf(X), computed by methods that avoid cancellation for large X.
Bugs
As these are the C library, the bugs are the same.
