Frac

Computes a signed fractional part for each element of a vector.

Syntax

IppStatus ippsFrac_32f (const Ipp32f*
pSrc
, Ipp32f*
pDst
, Ipp32s
len
);
IppStatus ippsFrac_64f (const Ipp64f*
pSrc
, Ipp64f*
pDst
, Ipp32s
len
);
Include Files
ippvm.h
Domain Dependencies
Headers:
ippcore.h
Libraries:
ippcore.lib
Parameters
pSrc
Pointer to the source vector.
pDst
Pointer to the destination vector.
len
Number of elements in the vectors.
Description
This function computes a fractional part of each element of the
pSrc
vector. The result is stored in the corresponding element of the
pDst
vector.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pSrc
or
pDst
pointer is
NULL
.
ippStsSizeErr
Indicates an error when
len
is less than, or equal to zero.

Example

The example below shows how to use the
ippsFrac
function.
IppStatus ippsFrac_32f_sample(void) { const Ipp32f x[4] = {-1.883, -0.265, 0.176, 1.752}; Ipp32f y[4]; IppStatus st = ippsFrac_32f ( x, y, 4 ); printf(" ippsFrac_32f:\n"); printf(" x = %.3f %.3f %.3f %.3f \n", x[0], x[1], x[2], x[3]); printf(" y = %.3f %.3f %.3f %.3f \n", y[0], y[1], y[2], y[3]); return st; }
Result:
ippsFrac_32f: x = -1.883 -0.265 0.176 1.752 y = -0.883 -0.265 0.176 0.752
