FUNCTION

# byte\_array.repeat

```signature
pure function repeat(n: integer): byte_array
```

Repeats this byte\_array `n` times.

Examples:

* `x'1234abcd'.repeat(3)` returns `x'1234abcd1234abcd1234abcd'`
* `x''.repeat(3)` returns `x''`
* `x'1234abcd'.repeat(0)` returns `x''`

**Parameters**

* **n** — the number of times to repeat this byte\_array

**Throws**

* `exception` — when: - `n` is negative - `n` is greater than `(2^31)-1` - the resulting byte array has size greater than `(2^31)-1`
