Hello Albert,

I suspect your question is actually "Why does GMP use separate functions
for integers and floats?" (GMP integers being different from int). As a
long-winded answer, please read "What Every Computer Scientist Should Know
About Floating-Point Arithmetic" (
http://docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html). Integers
and floating point numbers are represented quite differently from each
other.
