Reduce the chance that input objects sometimes could report an off by…

… 1 value

Fixed a situation where a 0.1 scale input number could cause the
VT change numeric value command to be off by 1 due to an implicit cast.
Fixed a situation where the VT change numeric value command could send
the wrong value for a number variable underlying an input number.
