NAME
sqrtf4 - return accurate square root of float elementsSYNOPSIS
Procedure call syntax:
| #include <simdmath.h> |
| vector float sqrtf4(vector float x); |
| Link with -lsimdmath |
Inline call syntax:
| #include <simdmath.h> |
| #include <sqrtf4.h> |
| vector float _sqrtf4(vector float x); |
| Parameters | |
| x | input vector |
DESCRIPTION
The sqrtf4 function computes the square roots of the elements of the input vectors.
On the SPU this is a fully compliant IEEE implementation guaranteeing the correct truncated result for all valid inputs.
Note: The PPU implementation does not produce IEEE accuracy.
RETURN VALUE
The function sqrtf4 returns
a float vector in which each element is defined as
