description: Type conversions for fractionalSecondDigits option
info: |
    sec-getoption steps 8–9:
      8. Else if _type_ is Number, then
        a. Set _value_ to ? ToNumber(value).
        b. ...
      9. Else,
        a. Set _value_ to ? ToString(value).
    sec-getstringornumberoption step 2:
      2. Let _value_ be ? GetOption(_options_, _property_, « Number, String », *undefined*, _fallback_).
    sec-temporal-tosecondsstringprecision step 9:
      9. Let _digits_ be ? GetStringOrNumberOption(_normalizedOptions_, *"fractionalSecondDigits"*, « *"auto"* », 0, 9, *"auto"*).
    sec-temporal.plaintime.prototype.tostring step 4:
      4. Let _precision_ be ? ToSecondsStringPrecision(_options_).
