So you are saying when constant propagation is on, an expression should have a
different result than with constant propagation off?
The result of math when using constants MUST be the same as the result of
identical math using variables.
There should never be a difference if I did my formula with hard coded
constants vs variables.
Const_Ans = 2.00000010627116630224
Const_Ans1 = 2.00000010627116630224
Var_Ans1 = 2.00000000000000000000
This should not be happening.

See my other post;
if the developer explicitly wants reduced precision, then this is what
happens.
But the reduced precision should not come unexpectedly simply because the
compiler attaches type attributes to constants (which can't be easily
explained),
and then the outcome of simple decimal arithmetic is incorrect.
So I have to disagree, sorry.
