Usually for fixed-point calculations it is faster to use the mpz layer.
A fixed point number f is represented by an integer m with an implicit
exponent e:

	  f = m / 2^e.

A floating-point addition is converted to an integer addition, a floating-point
multiplication to an integer multiplication followed by a division by 2^e
