## Radix Support

### Decimal (base 10)

```typescript theme={null}
Uint.toString(Uint(12345n))  // "12345"
```

### Hexadecimal (base 16)

```typescript theme={null}
Uint.toString(Uint(255n), 16)  // "ff" (no 0x prefix)
```

<Tip>
  For hex with `0x` prefix, use `toHex()` instead.
</Tip>

### Binary (base 2)

```typescript theme={null}
Uint.toString(Uint(15n), 2)  // "1111"
```

### Octal (base 8)

```typescript theme={null}
Uint.toString(Uint(64n), 8)  // "100"
```
