# Swift - llround() Function

The Swift llround() 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 llround(_ __x: Double) -> Int64
```

### 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 Int64 type.

### Example:

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

```import Foundation

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

The output of the above code will be:

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