# Integer Functions

Integers have multiple built-in functions you can use.

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

Returns the string representation of the integer.

```
    let answer = 42

    answer.toString()  // is "42"
```

\-

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

Returns the byte array representation (`[UInt8]`) in big-endian order of the integer.

```
    let largeNumber = 1234567890

    largeNumber.toBigEndianBytes()  // is `[73, 150, 2, 210]`
```
