Formats a numeric value (int or float) in a way that's compatible with the expected spreadsheet format.

Formatting of float values is locale dependent in PHP < 8.
Thousands separators and decimal points vary from locale to locale (en_US: 12.34 vs pl_PL: 12,34).
However, float values must be formatted with no thousands separator and a "." as decimal point
to work properly. This method can be used to convert the value to the correct format before storing it.
