To handle non-US locales while still supporting the documented behavior, we allow either a period or a comma as the decimal separator. This will be normalized to the decimal-point representation; internally indexMem is always either the string representation of an integer or one of the exact strings '0.25', '0.5', or '0.75' regardless of locale. Arguments: value (str): Value provided as an argument to the option. Returns: The memory setting as a string.
