# Swift - lround() Function

The Swift lround() function returns an integral value that is nearest to the argument value. In halfway cases, the argument is rounded away from zero.

### Syntax

In Foundation framework, it is defined as follows:

```public func lround(_ __x: Double) -> Int
```

### Parameters

 `x` Specify a value to round.

### Return Value

Returns an integral value by rounding up the x to nearby integral value then casted to Int type.

### Example:

In the example below, lround() function is used to round the given number.

```import Foundation

print("lround(10.4) = \(lround(10.4))")
print("lround(10.6) = \(lround(10.6))")
print("lround(10.5) = \(lround(10.5))")
print("lround(11.5) = \(lround(11.5))")
print("lround(12.5) = \(lround(12.5))")
print("lround(-10.5) = \(lround(-10.5))")
print("lround(-11.5) = \(lround(-11.5))")
print("lround(-12.5) = \(lround(-12.5))")
```

The output of the above code will be:

```lround(10.4) = 10
lround(10.6) = 11
lround(10.5) = 11
lround(11.5) = 12
lround(12.5) = 13
lround(-10.5) = -11
lround(-11.5) = -12
lround(-12.5) = -13
```
