  • Constructor Details

    • Rational

      public Rational(long numerator, long denominator)
      The arguments to this constructor are long in order to represent all possible 32-bit unsigned integers. Parameters greater than 2 ^ 32 - 1 are not meaningful.
      Parameters:
      numerator - numerator of the Rational value
      denominator - denominator of the Rational value
