Comparison Functions

Function: int mpf_cmp (mpf_t op1, mpf_t 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)

@ifnottex Compare op1 and op2. Return a positive value if op1 > op2, zero if op1 = op2, and a negative value if op1 < op2.

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 of op1 and op2 are approximately equal.

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.

Macro: int mpf_sgn (mpf_t op)

@ifnottex 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.
