# Address Functions

```
  fun toString(): String
```

Returns the string representation of the address.

```
    let someAddress: Address = 0x436164656E636521

    someAddress.toString()  // is "0x436164656E636521"
```

\-

```
  fun toBigEndianBytes(): [UInt8]
```

Returns the byte array representation (`[UInt8]`) of the address.

```
    let someAddress: Address = 0x436164656E636521

    someAddress.toString()  // is `[67, 97, 100, 101, 110, 99, 101, 33]`
```
