Description
Allows the performance of arbitrary based logarithms. See examples. On zero, returns -inf. Below zero, returns NaN, a special value that always causes failure when compared to other numbers. (ie. (NaN<0) -> false, (NaN>=0) -> false)<br/> other logarithms<br/> log(x,10) = log10(x)<br/> log(x,e) = ln(x)
Examples
trace(log(2 .5)) #prints '-1' trace(log(.25 .5)) #prints '2'
