DivC

Divides each element of a vector by a constant value.

Syntax

Case 1. Not-in-place operations on floating point data.

IppStatus ippsDivC_32f(const Ipp32f* pSrc, Ipp32f val, Ipp32f* pDst, int len);

IppStatus ippsDivC_64f(const Ipp64f* pSrc, Ipp64f val, Ipp64f* pDst, int len);

IppStatus ippsDivC_32fc(const Ipp32fc* pSrc, Ipp32fc val, Ipp32fc* pDst, int len);

IppStatus ippsDivC_64fc(const Ipp64fc* pSrc, Ipp64fc val, Ipp64fc* pDst, int len);

Case 2. Not-in-place operations on integer data with scaling.

IppStatus ippsDivC_8u_Sfs(const Ipp8u* pSrc, Ipp8u val, Ipp8u* pDst, int len, int ScaleFactor);

IppStatus ippsDivC_16u_Sfs(const Ipp16u* pSrc, Ipp16u val, Ipp16u* pDst, int len, int scaleFactor);

IppStatus ippsDivC_16s_Sfs(const Ipp16s* pSrc, Ipp16s val, Ipp16s* pDst, int len, int ScaleFactor);

IppStatus ippsDivC_16sc_Sfs(const Ipp16sc* pSrc, Ipp16sc val, Ipp16sc* pDst, int len, int ScaleFactor);

Case 3. In-place operations on floating point data.

IppStatus ippsDivC_32f_I(Ipp32f val, Ipp32f* pSrcDst, int len);

IppStatus ippsDivC_64f_I(Ipp64f val, Ipp64f* pSrcDst, int len);

IppStatus ippsDivC_32fc_I(Ipp32fc val, Ipp32fc* pSrcDst, int len);

IppStatus ippsDivC_64fc_I(Ipp64fc val, Ipp64fc* pSrcDst, int len);

Case 4. In-place operations on integer data with scaling.

IppStatus ippsDivC_8u_ISfs(Ipp8u val, Ipp8u* pSrcDst, int len, int ScaleFactor);

IppStatus ippsDivC_16u_ISfs(Ipp16u val, Ipp16u* pSrcDst, int len, int scaleFactor);

IppStatus ippsDivC_16s_ISfs(Ipp16s val, Ipp16s* pSrcDst, int len, int ScaleFactor);

IppStatus ippsDivC_64s_ISfs(Ipp64s val, Ipp64s* pSrcDst, Ipp32u len, int ScaleFactor);

IppStatus ippsDivC_16sc_ISfs(Ipp16sc val, Ipp16sc* pSrcDst, int len, int ScaleFactor);

Parameters

val	Scalar value used as a divisor.
pSrc	Pointer to the source vector.
pDst	Pointer to the destination vector.
pSrcDst	Pointer to the source and destination vector for in-place operation.
len	Number of elements in the vector
scaleFactor	Scale factor, refer to Integer Scaling.

Description

The function ippsDivC is declared in the ipps.h file. This function divides each element of the vector pSrc by a value val and stores the result in pDst.

The in-place flavors of ippsDivC divide each element of the vector pSrcDst by a value val and store the result in pSrcDst.

Functions with Sfs suffixes perform scaling of the result value in accordance with the scaleFactor value. If the output value exceeds the data range, the result becomes saturated.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pSrc, pDst, or pSrcDst pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
ippStsDivByZeroErr	Indicates an error when val is equal to 0.
