Example

s, err := New()

if err != nil {
	panic(err)
}

for i := range int64(10) {
	enc := s.Encode(i)
	dec, _ := s.Decode(enc)

	fmt.Printf("%02d = %s = %02d\n", i, enc, dec)
}

fmt.Println(strings.Repeat("-", 24))

for i := int64(math.MaxInt64 - 10); i < math.MaxInt64; i++ {
	enc := s.Encode(i)
	dec, _ := s.Decode(enc)

	fmt.Printf("%02d = %s = %02d\n", i, enc, dec)
}
