Swift program to convert double type variables to int

This tutorial will discuss how to write swift program to convert double type variable to int.

Swift support various datatypes and double and integers are one of them. Double is used to represent 64-bit floating point numbers. For example, 34.55656, 9.8283, etc. To create a double type variable we use Double keyword. Whereas Integer represent numeric values like 2, 3, 45, 6, etc. And to create integer type variable we use Int keyword.

To convert double type variable into int we uses Int() function. This function convert any data type into integer.


Following is the syntax −


Below is a demonstration of the same −


Suppose our given input is −

Num = 52.324


The desired output would be −

Integer = 52


The following program shows how to convert double type variable to int.

import Foundation
import Glibc

// Double type variable 
var mynum : Double = 73.93

// Convert double into integer 
// Using Int() function
var myVar = Int(mynum)

print("Integer:", myVar)
print("Type of myVar variable:", type(of: myVar))


Integer: 73
Type of myVar variable: Int
