divf4_fast

NAME

divf4_fast - fast return quotients of float elements

Procedure call syntax:

#include <simdmath.h>

vector float divf4_fast(vector float x, vector float y);

Link with -lsimdmath

Inline call syntax:

#include <simdmath.h>

#include <divf4_fast.h>

vector float _divf4_fast(vector float x, vector float y);

Parameters
x,y	input vectors

This functions divides each element of x by the corresponding element of y and returns a vector of the quotients.

Special Cases:

If either input is NaN the result is NaN.
For Inf/Inf or 0/0 the result is NaN.
For finite/0 the result is Inf with sign = sign(x)/sign(y).
For finite/Inf the result is 0 with sign = sign(x)/sign(y).
On the SPU division by 0 results in a return of HUGE_VALF with sign = sign(x)/sign(y).

The functiondivf4_fast returns a vector containing the quotients produced by dividing each element of x by the corresponding element of y.
