Ceil
Computes integer value rounded toward plus infinity for each vector element.
Syntax
IppStatus ippsCeil_32f (const Ipp32f* pSrc, Ipp32f* pDst, Ipp32s len);
IppStatus ippsCeil_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 an integer value rounded towards plus infinity for each element of the vector pSrc, and stores the result in the corresponding element of the vector pDst.
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 0. |
Example
The example below shows how to use the function ippsCeil.
IppStatus ippsCeil_32f_sample(void) { const Ipp32f x[4] = {-0.883, -0.265, 0.176, 0.752}; Ipp32f y[4]; IppStatus st = ippsCeil_32f ( x, y, 4 ); printf(" ippsCeil_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; }
Output:
ippsCeil_32f: x = -0.883 -0.265 0.176 0.752 y = 0.000 0.000 1.000 1.000
