/// @assertion String toStringAsFixed(int fractionDigits)
/// Returns a decimal-point string-representation of this.
///
/// Converts this to a double before computing the string representation.
///
/// If the absolute value of this is greater or equal to 10^21 then this methods
/// returns an exponential representation computed by
/// this.toStringAsExponential(). Otherwise the result is the closest string
/// representation with exactly fractionDigits digits after the decimal point.
/// If fractionDigits equals 0 then the decimal point is omitted.
///
/// The parameter fractionDigits must be an integer satisfying:
