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

Swift support various datatypes and double and string are one of them. String is an ordered collection of characters. For example: “TutorialsPoint”, “Pinky”, etc. To create a string type variable, we use String keyword. Whereas Double is used to represent 64-bit floating point numbers.

Below is a demonstration of the same −


Suppose our given input is −

Num = 52.324


The desired output would be −

String = 52.324


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

import Foundation
import Glibc

// Double type variable 
var mynum : Double = 73.93

// Convert double into string 
// Using String() function
var myVar = String(mynum)

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


String: 73.93
Type of myVar variable: String
