remquod2

NAME

remquod2 - return remainders and quotients from division of double elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector double remquod2(vector double x, vector double y, vector signed int *pquo);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <remquod2.h>

vector double _remquod2(vector double x, vector double y, vector signed int *pquo);

Parameters
x,y	input vectors
*pquo	pointer to quotient vector

DESCRIPTION

The remquod2 function returns the same vector as the corresponding remainderd2 function. In addition it places into *pquo a vector of values of which the sign of each is the sign of x/y, and the magnitude of each is the congruent modulo 2^n to the magnitude of the integral quotient of the corresponding element of x/y (where n is an implementation-defined integer greater than or equal to 3).

RETURN VALUE

The function remquod2 returns a double vector in which each element is defined as the exact remainder of x/y.

The integral quotient of the corresponding element of x/y mod n is placed in the corresponding element of the vector pointed to by *pquo. The first quotient is placed in slots 0 and 1. The second quotient is placed in slots 2 and 3.
