TS has trouble when two decimal values are compared (Val1 = Val2).
They are never truly equal if they are calculated from other numbers.
There are small errors from the precision of the computation. A
preferred approach is to allow a small error in the comparison:
Value3 = .000001 for example, then use:
if AbsValue (Value1 - Value2) < Value3 Then Value1 = 0;
This allows numbers to be "equal" within some error that will always
be there.
