Swift Double isMultiple()

In this tutorial, we will learn about the Swift Double isMultiple() method with the help of examples.

The isMultiple() method checks if one number is multiple of another or not.


// check is 9 is multiple of 3 or not var result = 9.isMultiple(of: 3)
print(result) // Output: true

isMultiple() Syntax

The syntax of the isMultiple() method is:

num.isMultiple(of: otherNumber)

Here, num is a number.

isMultiple() Parameters

The isMultiple() method takes one parameter

  • otherNumber - the value to test

isMultiple() Return Values

The isMultiple() method returns boolean value

  • true - if num is multiple of otherNumber
  • false - if num is not a multiple of otherNumber

Example 1: Swift Double isMultiple()

// check if 4 is multiple of 2 or not
var result1 = 4.isMultiple(of: 2)
print(result1) // check if 2 is multiple of 4 or not
var result2 = 2.isMultiple(of: 4)
print(result2) // check if 210 is multiple of 10 or not
var result3 = 210.isMultiple(of: 10)



Here, since 4 is a multiple of 2, the isMultiple() method returns true. However, 2 is not a multiple of 4, the method returns false.

Lastly, since 210 is multiple of 10, the method returns true.

Example 2: Check Odd or Even

// check if 48 is multiple of 2 or not if 48.isMultiple(of: 2) {
print("Even Number") } else { print("Odd number") }


Even Number

Here, since 48 is multiple of 2, the code inside the if block is executed.
