Golang mpz_tdiv_qr Examples

Example #1

File: gmp.go Project: edisonwsk/golang-on-cygwin

// DivModInt sets q = x / y and r = x % y.
func DivModInt(q, r, x, y *Int) {
	q.doinit()
	r.doinit()
	x.doinit()
	y.doinit()
	C.mpz_tdiv_qr(&q.i[0], &r.i[0], &x.i[0], &y.i[0])
}

Example #2

File: int.go Project: jamesadney/gmp

// QuoRem sets z to the quotient x/y and r to the remainder x%y
// and returns the pair (z, r) for y != 0.
// If y == 0, a division-by-zero run-time panic occurs.
//
// QuoRem implements T-division and modulus (like Go):
//
//	q = x/y      with the result truncated to zero
//	r = x - y*q
//
// (See Daan Leijen, ``Division and Modulus for Computer Scientists''.)
// See DivMod for Euclidean division and modulus (unlike Go).
//
func (z *Int) QuoRem(x, y, r *Int) (*Int, *Int) {
	x.doinit()
	y.doinit()
	r.doinit()
	z.doinit()
	C.mpz_tdiv_qr(z.ptr, r.ptr, x.ptr, y.ptr)
	return z, r
}
