Retrieve the logarithm of number in a specified base ?

If you want to get just the *integer* part of the logarithm of an 
*integer* over an *integer* base, maybe it is better to recursively 
divide, using just mpz integer functions.

Sketch of the idea
(assuming number is greater than base)
(and using standard notation, to be readable)

mpz_t number, base;
long exponent=0;
while (number>base)
return exponent;

The actual function to perform de division should be (i think) 

I hope you get the idea.
