 Description Each element of X is rounded to the nearest integer value. In case of a fractional part of exactly 0.5, the nearest even integer value is chosen and stored in Y. For example, 2.5 is rounded to 2, and 3.5 is rounded to 4. The functions VF_roundtoI,   VF_roundtoLI,   VF_roundtoU, etc. convert the result into the various integer data types.
 Error handling OVERFLOW and DOMAIN errors are handled "silently", i.e., without any error message and without being indicated by the return value. In the case of OVERFLOW errors, the result is set to the extreme value possible. Negative numbers in the versions VF_roundtoU,   VF_roundtoUB,   VF_roundtoUS,   VF_roundtoUL, and VF_roundtoUI (which would lead to DOMAIN errors) are handled by setting the result to 0.
 Return value always FALSE (0)
