islessgreaterd2

NAME

islessgreaterd2 - verify if double elements are less or greater

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector unsigned long long islessgreaterd2(vector double x, vector double y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <islessgreaterd2.h>

vector unsigned long long _islessgreaterd2(vector double x, vector double y);

Parameters
x	input vector
y	input vector

DESCRIPTION

The islessgreaterd2 function returns a vector in which each element indicates if the corresponding element of x is less than or greater than the corresponding element of y. This function correctly compares subnormal numbers.

Special Cases:

If either element is NaN the elements are considered unequal.

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

The values +0 and -0 are considered equal.

RETURN VALUE

The function islessgreaterd2 returns an unsigned long long vector in which each element is defined as:

ULLONG_MAX	if the element of x is less than or greater than the element of y.
0	otherwise.

ENVIRONMENT

SPU only

CONFORMING TO

SIMD Math library specification for the Cell Broadband Engine™ Architecture.
