This is a cool mod, thank you for making it! I especially appreciate the configurable settings.

I found a bug that results in a bad calculation when using decimal numbers. Example of how to reproduce this bug:

Step 1: Type 2+2 then enter
(The line is auto-cleared per configured setting, but the history keeps the previous calculation for 2+2)

Step 2: Type .0616 then enter
The calculator will incorrectly calculate 4.0616 instead. In other words, it erroneously merges the answer from the previous calculation.

Can you please fix this bug?
