isunorderedf4

NAME

isunorderedf4 - verify if float elements are unordered

Procedure call syntax:

#include <simdmath.h>

vector unsigned int isunorderedf4(vector float x, vector float y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <isunorderedf4.h>

vector unsigned int _isunorderedf4(vector float x, vector float y);

The isunorderedf4 function returns a vector in which each element indicates if the corresponding element of either x or y is unordered (NaN).

On the SPU single-precision NaN values are not representable. Therefore the function isunorderedf4 returns 0 for all input.

On the PPU the function isunorderedf4 returns an unsigned int vector in which each element is defined as:

UINT_MAX	if the element of either x or y is NaN.
0	otherwise.
