fmaxd2

NAME

fmaxd2 - return larger values of double elements

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>

vector double fmaxd2(vector double x, vector double y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <fmaxd2.h>

vector double _fmaxd2(vector double x, vector double y);

Parameters
x.y	input vectors

DESCRIPTION

The fmaxd2 functions returns a vector containing the larger (more positive) elements of x and y.

RETURN VALUE

The function fmaxd2 returns a double vector in which each element is defined as:

the larger (more positive) of the corresponding elements of x and y.
If one element is NaN and the other is numeric, the numeric value is returned.
If both elements are NaN, NaN is returned.

In double precision subnormals¹ equate to zero and so compare as equal. This means that the value returned may be either one of the subnormals, thereby making the following possibly true for two subnormal inputs:

fmaxd2(a, b) != fmaxd2(b, a)
