log
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. Eg. (NaN<0) -> false, (Nan>=0) -> false
other logarithms \
log(x,10) = log10(x) \
log(x,e) = ln(x)
Examples
trace(log(2 .5)) #prints '-1' trace(log(.25 .5)) #prints '2'
