    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.
