Rint
Computes rounded integer value in current rounding mode for each vector element with inexact result exception raised for each changed value.
Syntax
IppStatus ippsRint_32f (const Ipp32f* pSrc, Ipp32f* pDst, Ipp32s len);
IppStatus ippsRint_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 rounded integer value in a current rounding mode for each element of the vector pSrc, and stores the result in the corresponding element of the vector pDst raising inexact result exception if the value has changed.
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 ippsRint function.
#include <fenv.h> void ippsRint_32f_ sample(void) { const Ipp32f x[4] = {-1.883, -0.265, 0.176, 1.752}; Ipp32f y1[4], y2[4]; fesetround(FE_TONEAREST); ippsRint_32f ( x, y1, 4 ); fesetround(FE_TOWARDZERO); ippsRint_32f ( x, y2, 4 ); printf(" ippsRint_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]); }
Output:
ippsRint_32f: x = -1.883 -0.265 0.176 1.752 y1 = -2.000 0.000 0.000 2.000 y2 = -1.000 0.000 0.000 1.000
