Implementations of basic math functions which return NaN instead of throwing a DomainError.

Example:

import NaNMath
NaNMath.log(-100) # NaN
NaNMath.pow(-1.5,2.3) # NaN

In addition this package provides functions that aggregate arrays and ignore elements that are NaN. The following functions are implemented:

sum
maximum
minimum
extrema
mean
median
var
std
min
max

Example:

using NaNMath; nm=NaNMath
nm.sum([1., 2., NaN]) # result: 3.0
