Math

log

log(<-value <-base)

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'
