NAME
isnormalf4
- verify if float elements are normal
SYNOPSIS
Procedure
call syntax:
| #include <simdmath.h> |
| vector unsigned int isnormalf4(vector float x); |
| Link with -lsimdmath |
Inline call syntax:
| #include <simdmath.h> |
| #include <isnormalf4.h> |
| vector unsigned int _isnormalf4(vector float x); |
| Parameters |
|
| x |
input vector |
DESCRIPTION
The isnormalf4 function
returns a vector in which each element indicates if the corresponding element
of x is normal (not subnormal, Inf or NaN).
RETURN VALUE
On the SPU single-precision Inf and NaN values
are not representable. Therefore the function isnormalf4 returns UINT_MAX for
all input.
On the PPU the function
isnormalf4 returns an unsigned
int vector in which each element is defined as:
| UINT_MAX |
if the element of x is
normal. |
| 0 |
otherwise. |
