- **
- ** A multiprecision rational constant.
- ** This stores the rational as a pair of multiprecision integers,
- ** one for the numerator and one for the denominator.
- ** The number is always stored so that the gcd of the numerator and denominator
- ** is 1.  (This is referred to as referred to as canonical form in GMP's
- ** literature.) A consquence is that that the numerator and denominator may be
- ** different than the values used to construct the Rational.
