As discussed by the CIERMag group, it was suggested by Alberto and Edson to: - restrict the decimal separator to only ``.`` for now, instead of allowing ``.`` and ``,``. This intends to keep the PyMR framework restricted to only one locale (USA) instead of generating ambiguity between Brazillian / European / American standards. I think we can restrict it for now, since the spinbox is only being used by CIERMag, but we should implement a logic to be aware of the User locale and use this to define: - thousand separator - decimal separator The unit separator should remain defined statically in the code or programatically through a function like ``set_unit_separator``. Implementing this locale logic will ensure that all use cases are satisfied in all countries, despite the American standard being the most used one. ## Considerations - restricting the decimal separator to ``.`` will only require to edit one character in the validator regex - adding support for locale will require more work and refactoring of the validator / number interpretation logic (we currently have THOUSAND_SEPARATOR and UNIT_SEPARATOR constants defined but no DECIMAL_SEPARATOR constant)
