This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# Rational.rationalize (from ruby core) --- rat.rationalize -> self rat.rationalize(eps) -> rational --- Returns a simpler approximation of the value if the optional argument `eps` is given (rat-|eps| <= result <= rat+|eps|), self otherwise. r = Rational(5033165, 16777216) r.rationalize #=> (5033165/16777216) r.rationalize(Rational('0.01')) #=> (3/10) r.rationalize(Rational('0.1')) #=> (1/3)
