The following example is for when In is UINT#123.
If you use a different data type for In and Out, make sure the valid range of Out includes the valid range
of In. Otherwise, an error will not occur and the value of Out will be an illegal value. For example, if the
value of In is SINT#-128 and the data type of Out is INT, the value of Out will be INT#-128 instead of
INT#128.
