void fmpq_addmul(fmpq_t res, const fmpq_t op1, const fmpq_t op2)source
void fmpq_submul(fmpq_t res, const fmpq_t op1, const fmpq_t op2)source
void _fmpq_addmul(fmpz_t rnum, fmpz_t rden, const fmpz_t op1num, const fmpz_t op1den, const fmpz_t op2num, const fmpz_t op2den)source

Set the result to \mathit{res} + \mathit{op1} \cdot \mathit{op2} or \mathit{res} - \mathit{op1} \cdot \mathit{op2}. The product is formed in a temporary, so any aliasing is allowed (except, in the underscore versions, a numerator with a denominator).
