Swift program to find the Euler's number raised to a given exponent

Here, we are going to learn how to find the Euler's number raised to a given exponent in Swift programming language?
Submitted by Nidhi, on June 23, 2021

Problem Solution:

Here, we will use the exp() function to find the Euler's number raised to a given exponent and print the result on the console screen.

Program/Source Code:

The source code to find the Euler's number raised to a given exponent is given below. The given program is compiled and executed successfully.

// Swift program to find the Euler's number raised 
// to a given exponent

import Swift
import Foundation

var num:Double =  5.0
var res:Double =  0.0

res = exp(num)

print("Result: ",res)

Output:

Result:  148.4131591025766

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

To use mathematics and some standard functions, we need to import the foundation package using the below statement,

import Foundation;

Here, we created two double type variables num, res that are initialized with 5.0,0.0 respectively. Then we found the Euler's number raised to a given exponent using the exp() function and printed the result on the console screen.
