(Rational.new 22 12) ; => (Rational 11/6)
(Rational.mul (Rational.new 22 12) (Rational.new 1 6)) ; => (Rational 2/1)
(Rational.to-int (Rational.new 2 1)) ; => 2
(Rational.to-float (Rational.new 1 4)) ; => 0.25Please note that conversion can be lossy, because conversion to integer throws away any non-real value and conversion to floating point values is only as accurate as floating point numbers are.
Have fun!
