    /** Convert string content to numeric value.

        In any case, if rError is set 0.0 is returned.

        If nStringNoValueError is errCellNoValue, that is unconditionally
        assigned to rError and 0.0 is returned. The caller is expected to
        handle this situation. Used by the interpreter.

        Usually errNoValue is passed as nStringNoValueError.

        Otherwise, depending on the string conversion configuration different
        approaches are taken:


        For ScCalcConfig::StringConversion::ILLEGAL
        The error value passed in nStringNoValueError is assigned to rError
        (and 0.0 returned).


        For ScCalcConfig::StringConversion::ZERO
        A zero value is returned and no error assigned.


        For ScCalcConfig::StringConversion::LOCALE

        If the string is empty or consists only of spaces, if "treat empty
        string as zero" is set 0.0 is returned, else nStringNoValueError
        assigned to rError (and 0.0 returned).

        Else a non-empty string is passed to the number formatter's scanner to
        be parsed locale dependent. If that does not detect a numeric value
        nStringNoValueError is assigned to rError (and 0.0 returned).

        If no number formatter was passed, the conversion falls back to
        UNAMBIGUOUS.


        For ScCalcConfig::StringConversion::UNAMBIGUOUS

        If the string is empty or consists only of spaces, if "treat empty
        string as zero" is set 0.0 is returned, else nStringNoValueError
        assigned to rError (and 0.0 returned).

        If the string is not empty the following conversion rules are applied:

        Converted are only integer numbers including exponent, and ISO 8601 dates
        and times in their extended formats with separators. Anything else,
        especially fractional numeric values with decimal separators or dates other
        than ISO 8601 would be locale dependent and is a no-no. Leading and
        trailing blanks are ignored.

        The following ISO 8601 formats are converted:

        CCYY-MM-DD
        CCYY-MM-DDThh:mm
        CCYY-MM-DDThh:mm:ss
        CCYY-MM-DDThh:mm:ss,s
        CCYY-MM-DDThh:mm:ss.s
        hh:mm
        hh:mm:ss
        hh:mm:ss,s
        hh:mm:ss.s

        The century CC may not be omitted and the two-digit year setting is not
        taken into account. Instead of the T date and time separator exactly one
        blank may be used.

        If a date is given, it must be a valid Gregorian calendar date. In this
        case the optional time must be in the range 00:00 to 23:59:59.99999...
        If only time is given, it may have any value for hours, taking elapsed time
        into account; minutes and seconds are limited to the value 59 as well.

        If the string can not be converted to a numeric value, the error value
        passed in nStringNoValueError is assigned to rError.


        @param rStr
            The string to be converted.

        @param rConfig
            The calculation configuration.

        @param rError
            Contains the error on return, if any. If an error was set before
            and the conversion did not result in an error, still 0.0 is
            returned.

        @param nStringNoValueError
            The error value to be assigned to rError if string could not be
            converted to number.

        @param pFormatter
            The number formatter to use in case of
            ScCalcConfig::StringConversion::LOCALE. Can but should not be
            nullptr in which case conversion falls back to
            ScCalcConfig::StringConversion::UNAMBIGUOUS and if a date is
            detected the null date is assumed to be the standard 1899-12-30
            instead of the configured null date.

        @param rCurFmtType
            Can be assigned a format type in case a date or time or date+time
            string was converted, e.g. css::util::NumberFormat::DATE or
            css::util::NumberFormat::TIME or a combination thereof.
