log(a) / log(n) is not that much harder, and its the right way, imho. Yes, you're right that it is the right way. But for example, for tan(x), the "right way" is sin(x)/cos(x).

(Not such a good example, but anyway)

As you said :-) as an anal note, tan(x) is the correct notation, just as logarithms are also a wrapper type in themselves, log is also the "correct" notation.

log($bla,2) is cleaner, IMO, than log($bla)/log(2), not mentioning the possible need for extra ( and ).

yeah, I guess, its just an extra level of abstraction I don't think is necessary, but I don't really care all that much :-)

log2() is going too far IMO, that's why I believe it shouldn't exist. Why not move the more complex functions into a separate "math" extension or statistics extension? There is a possibility that GSL will be implemented in PHP, but that's in the 'idea to maybe do that stage' (of Jesus).

However, IMO the log, exp, sinus, etc. functions should be in the core.

Yes, I agree, however, expm1 and log1p don't. -Sterling
