# *=(_:_:)

Multiplies two values and stores the result in the left-hand-side
variable.

```
static func *= (lhs: inout Int8, rhs: Int8)
```

## Parameters

`lhs`

The first value to multiply.

`rhs`

The second value to multiply.

## Discussion

The product of the two arguments must be representable in the arguments’
type. In the following example, the result of `21 * 21` is greater than
the maximum representable `Int8` value:

```
var x: Int8 = 21
x *= 21
// Overflow error
```

> Note: Overflow checking is not performed in `-Ounchecked` builds.
