| Function | Rounding to the next whole number that is greater or equal. |

| Syntax C/C++ | #include <VFmath.h>
int VF_ceil( fVector Y, fVector X, ui size );

| Description | Each element of X is rounded to the nearest whole number that is greater than or equal to the input number and the result stored in Y. The functions VF_ceiltoI, VF_ceiltoLI, VF_ceiltoU etc. convert the result into the various integer data types (in the cases mentioned, to int, long int, and unsigned, resp.). |
|
| Error handling | OVERFLOW errors are handled by setting the result to the extreme value possible. Negative numbers in the versions VF_ceiltoU, VF_ceiltoUS, VF_ceiltoUL, and VF_ceiltoUI lead to DOMAIN errors; they are handled by setting the result to 0. |
|
| Return value | FALSE (0), if no error occurred, otherwise TRUE (non-zero). |
