remainderf4

NAME

remainderf4 - return remainders from division of float elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector float remainderf4(vector float x, vector float y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <remainderf4.h>

vector float _remainderf4(vector float x, vector float y);

Parameters
x,y	input vectors

DESCRIPTION

The remainderf4 function computes the remainder x REM y required by IEC 60559: When y 0 the remainder r = x REM y is defined regardless of the rounding mode by the mathematical relation r = x - ny, where n is the integer nearest the exact value of x/y; whenever |n - x /y| = 1/2 then n is even. Thus the remainder is always exact. If r = 0 its sign shall be that of x.

RETURN VALUE

The function remainderf4 returns a float vector in which each element is defined as the exact remainder of x/y.
