#4 Error when using Mod with a calculated value

[Irwan Amir Widjaja]

When using the result of an expression with the Mod
operator I get a "malformed expression" error.

For example:

I push the keys 3,*,3,=

and the display says 9

I now push the keys Mod,6,=

the display says 9 Mod 6 but instead of giving me the
result it gives an error.

Im running gcalctool 5.8.16.
