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 results:
ippsCeil_32f:
x = -0.883 -0.265 0.176 0.752
y = 0.000 0.000 1.000 1.000
