# +(_:_:)

Adds two values and produces their sum, rounded to a
representable value.

```
static func + (lhs: Float80, rhs: Float80) -> Float80
```

## Parameters

`lhs`

The first value to add.

`rhs`

The second value to add.

## Discussion

The addition operator (`+`) calculates the sum of its two arguments. For
example:

```
let x = 1.5
let y = x + 2.25
// y == 3.75
```

The `+` operator implements the addition operation defined by the
[IEEE 754 specification](http://ieeexplore.ieee.org/servlet/opac?punumber=4610933).
