- * call-seq:
- *   rat.coerce(numeric)  =>  array
- *
- * If _numeric_ is a +Rational+ object, returns an +Array+ containing _rat_
- * and _numeric_. Otherwise, returns an +Array+ with both _rat_ and _numeric_
- * represented in the most accurate common format. This coercion mechanism is
- * used by Ruby to handle mixed-type numeric operations: it is intended to
- * find a compatible common type between the two operands of the operator.
- *
- * For example:
- *
- *     Rational(2).coerce(Rational(3))  #=> [(2), (3)]
- *     Rational(5).coerce(7)            #=> [(7, 1), (5, 1)]
- *     Rational(9, 8).coerce(4)         #=> [(4, 1), (9, 8)]
- *     Rational(7, 12).coerce(9.9876)   #=> [9.9876, 0.5833333333333334]
- *     Rational(4).coerce(9/0.0)        #=> [Infinity, 4.0]
- *     Rational(5, 3).coerce('string')  #=> TypeError: String can't be
- *                                      #   coerced into Rational
