mathematical values rather than Numbers: * `ResolvePlural` * `ResolvePluralRange` This brings `Intl.PluralRules`'s behaviour into alignment with `Intl.NumberFormat`'s. Making this change has the following benefits: * Allows `Intl.PluralRules` to handle BigInts as well as numbers * Use of `ToIntlMathematicalValue` AO allows exact decimal values to be represented

When a rounding mode is set, there's an observable difference in implementations when <tc39/ecma402#1026> is not supported.
