islessd2

NAME

islessd2 - verify if double elements are less

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector unsigned long long islessd2(vector double x, vector double y);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <islessd2.h>
vector unsigned long long _islessd2(vector double x, vector double y);
Parameters  
x input vector
y input vector

DESCRIPTION

The islessd2 function returns a vector in which each element indicates if the corresponding element of x is less than the corresponding element of y. These functions correctly compare subnormal values.

Special cases:

If either element is NaN, the comparison is false.

RETURN VALUE

The function islessd2 returns an unsigned long long vector in which each element is defined as:
ULLONG_MAX if the element of x is less than the corresponding element of y.
0 otherwise.

ENVIRONMENT

SPU only

CONFORMING TO

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