[Bug]: Math Region settings not being used in input #835

Describe the bug

When typing quantities to create math expressions with the Spanish region selected doesn't' use the Spanish locale for decimal quantities. In the US you would put 2.50 but in Europe we use 2,50. If I use the coma when entering quantities massCode doesn't recognize them (no result in the right column), but if I use the dot it computes the operation and shows the result in the right with a coma, so it knows that in preferences is selected Spanish region.

To reproduce

1. Go to ... Math Notebook
2. Click on ... a notebook and put some decimal numbers but using coma as a separator
3. Do some math operation with those decimal numbers
4. See error… no value appears at the right (no result).
