islessequalf4

NAME

islessequalf4 - verify if float elements are less or equal

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector unsigned int islessequalf4(vector float x, vector float y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <islessequalf4.h>

vector unsigned int _islessequalf4(vector float x, vector float y);

Parameters
x	input vector
y	input vector

DESCRIPTION

The islessequalf4 function returns a vector in which each element indicates if the corresponding element of x is less than or equal to the corresponding element of y. This function correctly compares subnormal values.

Special cases:

If either element is NaN the comparison is false.

If both elements are infinite with the same sign the elements are considered equal.

The values +0 and -0 are considered equal.

RETURN VALUE

The function islessequalf4 returns an unsigned int vector in which each element is defined as:

UINT_MAX	if the element of x is less than or equal to the corresponding element of y.
0	otherwise.

ENVIRONMENT

SPU and PPU
