Comparison Functions
====================
*- Function: int mpf_cmp (mpf_t OP1, mpf_t OP2)*
*- Function: int mpf_cmp_d (mpf_t OP1, double OP2)*
*- Function: int mpf_cmp_ui (mpf_t OP1, unsigned long int OP2)*
*- Function: int mpf_cmp_si (mpf_t OP1, signed long int OP2)*
Compare OP1 and OP2. Return a positive value if OP1 > OP2, zero
if OP1 = OP2, and a negative value if OP1 < OP2.
`mpf_cmp_d' can be called with an infinity, but results are
undefined for a NaN.
*- Function: int mpf_eq (mpf_t OP1, mpf_t OP2, unsigned long int op3)*
Return non-zero if the first OP3 bits of OP1 and OP2 are equal,
zero otherwise. I.e., test if OP1 and OP2 are approximately equal.
Caution: Currently only whole limbs are compared, and only in an
exact fashion. In the future values like 1000 and 0111 may be
considered the same to 3 bits (on the basis that their difference
is that small).
*- Function: void mpf_reldiff (mpf_t ROP, mpf_t OP1, mpf_t OP2)*
Compute the relative difference between OP1 and OP2 and store the
result in ROP. This is abs(OP1-OP2)/OP1.
*- Macro: int mpf_sgn (mpf_t OP)*
Return +1 if OP > 0, 0 if OP = 0, and -1 if OP < 0.
This function is actually implemented as a macro. It evaluates
its arguments multiple times.
