Minor Bug still present in new version - constants in CAS mode

[Nigel (UK)]

Thanks for all the bug fixes and improvements. Some of the changes to the way the CAS handles small approximate numbers have made me very happy! The work that has gone into this is appreciated.

I'm noticed one minor bug that is still present. Using the Units -> Const menu to enter constants with negative exponents in CAS mode still leads to a red error box on the screen. If the constant is manually edited to replace the '-' sign with the subtraction '-' sign, the error disappears.

For example, in CAS mode go to Units -> Const -> Physics -> 3. This enters epsilon-zero (8.85...E-12) into the command line. Pressing Enter gives an error.
