Can selection fields save floats to the DB or just integers and strings?

Question

Hello, I am creating a module with a selection field. I would like a float number to be saved to the DB when a user selects a choice from the selection drop down, but when I make a selection then I get an error like this:

DataError: invalid input syntax for integer: "0.25"

So my question is, can floating numbers be used as values for a selection field, or can you use only integers or strings? Thank you

Yes Selection Field value save characters or Integer in Database.

*Format of the selection parameter: tuple of tuples of strings of the form:
(('key_or_value', 'string_to_display'), ... )*

The below code shows display float value as string in Front view and Back-end store key value.

'type': fields.selection([('CodeA', '0.25'), ('CodeB', '0.50')], 'Type'),
