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
