Hi, I've got the following suggestion, about some of the new math-functions recently added: log2 and log10: remove from PHP exp2 and exp10: remove from PHP (the pow-way is also simply better, in the case of exp2/10, that is) Add second parameter to log, to specify base. (better than writing log(a)/log(b)) Optional: add second parameter to exp, to specify base. I am not in favor of the latter one, since exp(exp,base) === pow(base,exp). But for consistency with log, you could argue to do so. Remove cbrt?, isn't used much, and the name isn't as familiar as sqrt. expm1, log1p: Could be useful for some people, so leave them there.

log(a) / log(n) is not that much harder, and its the right way, imho. Why not move the more complex functions into a separate "math" extension or statistics extension? -Sterling
