Rational numbers are represented as the quotient of arbitrarily large numerators and denominators. Rationals are canonicalized such that the denominator and the numerator have no common factors, and that the denominator is positive. Zero has the unique representation 0/1.

NOTE: To use BigRational, you must explicitly import it with require "big"

require "big"

r = BigRational.new(7.to_big_i, 3.to_big_i)
r.to_s # => "7/3"

r = BigRational.new(3, -9)
r.to_s # => "-1/3"

It is implemented under the hood with GMP.
