~~NOTOC~~ <=[[4rpl:start| Index]] \\ <= [[4rpl:start#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' <=[[4rpl:start| Index]]
