## Function Syntax

* `word swapWord(word x); // form 1`
* `int swapInt(int x); // form 2`
* `dword swapDWord(dword x); // form 3`
* `long swapLong(long x); // form 4`
* `int64 swapInt64(int64 x); // form 5`
* `qword swapQWord(qword x); // form 6`

## Description

Swaps bytes of parameters. CAPL arithmetics follows the "little-endian-format" (Intel). The swap-functions serve for swapping bytes for the transition to and from the "big-endian-format" (Motorola).

## Parameters

Value whose bytes are to be swapped.

## Return Values

Value with swapped bytes.

## Example

```plaintext theme={null}
bigEndian = swapInt(1234); // create constant 1234 for Motorola processors
```
