# Base 62 Encoder
## Usage
```go
import "github.com/webermarci/base62"
var number uint64 = 1665401943785138000
encoded := base62.Encode(number)
// 1z1Yd99Ld0i
decoded, err := base62.Decode(encoded)
// 1665401943785138000
```
## Performance
It's a bit faster than the standard `math/big.Int` implementation.
