hypotf4

NAME

hypotf4 - return hypotenuse lengths for float catheti

SYNOPSIS

Procedure call syntax:

#include <simdmath.h>
vector float hypotf4(vector float x, vector float y);
Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>
#include <hypotf4.h>
vector float _hypotf4(vector float x, vector float y);
Parameters  
x, y Vectors containing the lengths of catheti (sides) from which the hypotenuses are to be calculated.

DESCRIPTION

The hypotf4 function returns a vector of sqrt(x^2+y^2) for corresponding elements of x and y.

RETURN VALUE

The function hypotf4 returns a float vector in which each element is defined as the square root of the sum of the squares of the corresponding elements of x and y, without undue overflow or underflow.
