# Extend Math.log to allow for bases != e

As Math.log currently stands, it’s a bit useless. It only calculates natural logarithms (base e). We can easily modify it however, to calculate logarithms of any base: Math.log = (function() { var log = Math.log; return function(n, a) { return log(n)/(a? log(a) : 1); } })(); We can now specify the base as a second […]
