| Description | Each element of X is rounded to the nearest whole number that is less than or equal to the input number and the result stored in Y. The functions VF_floortoI, VF_floortoLI, VF_floortoU, etc. convert the result to the various integer data types (in the cases mentioned, to the types int, long int, or unsigned, respectively). |
|
| Error handling | OVERFLOW errors are handled by setting the result to the extreme value possible. Negative numbers in the versions VF_floortoU, VF_floortoUS, VF_floortoUL, and VF_floortoUI 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). |
