isequalf4

NAME

isequalf4 - verify if float elements are equal

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector unsigned int isequalf4(vector float x, vector float y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <isequalf4.h>

vector unsigned int _isequalf4(vector float x, vector float y);

Parameters
x	input vector
y	input vector

DESCRIPTION

The isequalf4 function returns a vector in which each element indicates if the corresponding elements of x and y are equal. This function correctly compares subnormal numbers.

Special Cases:

NaNs always compare as unequal.

zeros compare as equal regardless of sign.

infinities compare as equal if they have the same sign.

RETURN VALUE

The function isequalf4 returns an unsigned int vector in which each element is defined as:

UINT_MAX	if the elements of x and y are equal.
0	otherwise.

ENVIRONMENT

SPU and PPU
