# Fixed-Point Number Functions

Fixed-Point numbers have multiple built-in functions you can use.

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

Returns the string representation of the fixed-point number.

```
    let fix = 1.23

    fix.toString()  // is "1.23000000"
```

\-

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

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

```
    let fix = 1.23

    fix.toBigEndianBytes()  // is `[0, 0, 0, 0, 7, 84, 212, 192]`
```
