In this tutorial, we are going to learn about how to round a double to its nearest Int in Swift.
We can round a double to the nearest Int by using the
round() method in Swift.
Here is an example, that rounds the double
15.3 to the nearest integer
import Foundation var a = 15.3 a.round() print(a)
If the decimal value is
>=.5 then it rounds up to the nearest value. for example, it rounds the
import Foundation var b = 15.7 b.round() print(b) // 16.0
round() method modifies the original value assigned to the variable, if you want to preserve an original value then you can use the
import Foundation var b = 15.7 var c = b.rounded() print(b) // 15.7 print(c) // 16.0
