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);

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
