    > gamma(5)

    methods

    var gamma = require('gamma')

    gamma(z)

    Return the gamma function over z. Complex numbers aren't supported, only reals.

    gamma.log(z)

    Return the natural log of the gamma function for z.

    This function is used internally by the spouge approximation to compute large values.

    install
