divu4

NAME

divu4 - return quotients of unsigned integer elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

divu4_t divu4(vector unsigned int x, vector unsigned int y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <divu4.h>

divu4_t _divu4(vector unsigned int x, vector unsigned int y);

Parameters
x,y	input vectors

DESCRIPTION

The divu4 function divides each element of x by the corresponding element of y and returns a vector of remainders in a structure (if the quotients can be represented).

Special Cases:

Division by zero (positive or negative) produces positive zero, without generating an error.
Negative zero divided by 1 produces zero.

RETURN VALUE

The function divu4 returns the quotient and remainder in the following structures:

	typedef struct divi4_t {
	vector signed int quot;
	vector signed int rem;
	} divi4_t;

	typedef struct divu4_t {
	vector unsigned int quot;
	vector unsigned int rem;
	} divu4_t;

Each element in the structure member quot is the algebraic quotient truncated towards 0.
Each element in the structure member rem is the corresponding remainder, such that x = quot*y+rem
