Module summary

Mathematical functions.

Description

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

Exports

acos(X) -> float()acosh(X) -> float()asin(X) -> float()asinh(X) -> float()atan(X) -> float()atan2(Y, X) -> float()atanh(X) -> float()cos(X) -> float()cosh(X) -> float()exp(X) -> float()log(X) -> float()log10(X) -> float()log2(X) -> float()pow(X, Y) -> float()sin(X) -> float()sinh(X) -> float()sqrt(X) -> float()tan(X) -> float()tanh(X) -> float()

Types:

Y = X = number()

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

erf(X) -> float()

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.

erfc(X) -> float()

Types:

X = number()

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

pi() -> float()

A useful number.

Limitations

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