ios - Check if number is decimal with swift

Question

How can i check if a number is decimal or not using swift?

With Objective-C:

if (number == (int) number) {
  //decimal
}
else {
  //not decimal
}

Answer 1

extension FloatingPoint {
  var isInteger: Bool { rounded() == self }
}

(You'll also need to use the return keyword if you're not using Swift 5.1 or later.)
