Swift Program to convert int type variable to double

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

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 int type variable into double we uses Double() function. This function convert any data type into double.


Following is the syntax −


Below is a demonstration of the same −


Suppose our given input is −

Num = 52324


The desired output would be −

Double = 52324.0


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

import Foundation
import Glibc

// Integer type variable 
var mynum : Int = 7393

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

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


Double: 7393.0
Type of myVar variable: Double
