# ^=(_:_:)

Stores the result of performing a bitwise XOR operation on the two given
values in the left-hand-side variable.

```
static func ^= (a: inout Int128, b: Int128)
```

## Discussion

A bitwise XOR operation, also known as an exclusive OR operation, results
in a value that has each bit set to `1` where *one or the other but not
both* of its arguments had that bit set to `1`. For example:

```
var x: UInt8 = 5          // 0b00000101
let y: UInt8 = 14         // 0b00001110
x ^= y                    // 0b00001011
```
