Modf
Computes truncated integer value and remaining fraction part for each vector element.
Syntax
IppStatus ippsModf_32f (const Ipp32f* pSrc, Ipp32f* pDst1, Ipp32f* pDst2, Ipp32s len);
IppStatus ippsModf_64f (const Ipp64f* pSrc, Ipp64f* pDst1, Ipp64f* pDst2, Ipp32s len);
Include Files
ippvm.h
Domain Dependencies
Headers: ippcore.h
Libraries: ippcore.lib
Parameters
pSrc |
Pointer to the source vector. |
pDst1 |
Pointer to the first destination vector. |
pDst2 |
Pointer to the second destination vector. |
len |
Number of elements in the vectors. |
Description
This function computes a truncated value and a remainder of each element of the vector pSrc. The truncated integer value is stored in the corresponding element of the pDst1 vector and the remainder is stored in the corresponding element of the pDst2 vector.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when pSrc or pDst1 or pDst2 pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to 0. |
Example
The example below shows how to use the function ippsModf.
IppStatus ippsModf_32f_sample(void) { const Ipp32f x[4] = {-1.883, -0.265, 0.176, 1.752}; Ipp32f y1[4], y2[4]; IppStatus st = ippsModf_32f ( x, y1, y2, 4 ); printf(" ippsModf_32f:\n"); printf(" x = %.3f %.3f %.3f %.3f \n", x[0], x[1], x[2], x[3]); printf(" y1 = %.3f %.3f %.3f %.3f \n", y1[0], y1[1], y1[2], y1[3]); printf(" y2 = %.3f %.3f %.3f %.3f \n", y2[0], y2[1], y2[2], y2[3]); return st; }
Output results:
ippsModf_32f: x = -1.883 -0.265 0.176 1.752 y1 = -1.000 0.000 0.000 1.000 y2 = -0.883 -0.265 0.176 0.752
