The following numeric types are supported:

	Int    signed integers
	Rat    rational numbers
	Float  floating-point numbers

The zero value for an [Int], [Rat], or [Float] correspond to 0. Thus, new
values can be declared in the usual ways and denote 0 without further
initialization:

	var x Int        // &x is an *Int of value 0
	var r = &Rat{}   // r is a *Rat of value 0
	y := new(Float)  // y is a *Float of value 0

}

// GobDecode implements the [encoding/gob.GobDecoder] interface.
func (z *Rat) GobDecode(buf []byte) error {
	if len(buf) == 0 {
		// Other side sent a nil or default value.
		*z = Rat{}
		return nil
	}
	if len(buf) < 5 {
		return errors.New("Rat.GobDecode: buffer too small")
	}
	b := buf[0]
	if b>>1 != ratGobVersion {
		return fmt.Errorf("Rat.GobDecode: encoding version %d not supported", b>>1)
	}
	const j = 1 + 4

	for _, test := range encodingTests {
		medium.Reset() // empty buffer for each test case (in case of failures)
		var tx Rat
		tx.SetString(test + ".14159265")
		if err := enc.Encode(&tx); err != nil {
			t.Errorf("encoding of %s failed: %s", &tx, err)
			continue
		}
		var rx Rat
		if err := dec.Decode(&rx); err != nil {
			t.Errorf("decoding of %s failed: %s", &tx, err)
			continue
		}
		if rx.Cmp(&tx) != 0 {
