sorry about the late reaction.

I checked that section,  however it says "Return the size of 'op' 
measured in number of digits in the given base"

However that is not what I want to know.  I want to know if I use an
mpz_t integer what it's actual size (in bytes) in memory is, not the 
number of digits it has in a certain base.
