| Description | Each element of X is rounded to an integer number by "chopping off" the fractional part. For example, -3.9 yields -3, and +3.9 yields +3. The result is stored in Y. The functions VF_choptoI, VF_choptoLI, etc. convert the result into the various integer data types. |
|
| Error handling | OVERFLOW errors are handled by setting the result to the extreme value possible. Negative numbers in the versions VF_choptoU, VF_choptoUS, VF_choptoUL, and VF_choptoUI 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). |
