[REF]main.py: fix generated VALUE formula in `__prepare_calc_formulas` function
Created originally on Bitbucket by z_makrelouf (Zakaria Makrelouf)
Was already merged in Bitbucket before import, marked as merged by the import user
If the Genshi expressions generates a number value (float or integer), the generated formula will be =VALUE("1.1")
which is problematic if the user machine is configured to use a decimal separator different than the .
. With this fix the generated formula will be =VALUE(1.1)
(without the quotes) which is correctly handled with by the .ods
format.
