Add two Complex Numbers in JavaScript

JavaScript Program to Add Two Complex Numbers is today topic of discussion in our tutorial. Now, let’s start with basic concepts.

JavaScript Program to Add Two Complex Numbers

Let’s see a JavaScript Program to Add Two Complex Numbers. Output The output of two complex numbers: 8+7!

Pseudocode of Program to Add Two Complex Numbers

1. function Complex(real1, imaginary1)
2.   this.real1 = 0
3.   this.imaginary1 = 0
4.   this.real1 = (typeof real1 === ‘undefined’) ? this.real1 : parseFloat(real1)
5.   this.imaginary1 = (typeof imaginary1 === ‘undefined’) ? this.imaginary1 : parseFloat(imaginary1)
6. Complex.transform = function(num)
7.   var complex;
8.   complex = (num instanceof Complex) ? num : complex
9.   complex = (typeof num === ‘number’) ? new Complex(num, 0) : num
10.   return complex
11. function display_complex(re, im)
12.   if(im === ‘0’) return ” + re
13.   if(re === 0) return ” + im + ‘i’
14.   if(im < 0) return ” + re + im + ‘i’
15.   return ” + re + ‘+’ + im + ‘i’
16. function complex_num_add(first, second)
17.   var num1 num2
18.   num1 = Complex.transform(first)
19.   num2 = Complex.transform(second)
20.   var real1 = num1.real1 + num2.real1
21.   var imaginary1 = num1.imaginary1 + num2.imaginary1
22.   return display_complex(real1, imaginary1)
23.  var a = new Complex(4, -5)
24.  var b = new Complex(4,  3)
25. console.log(complex_num_add(a,b))

Algorithm of Program to Add two Complex Numbers

Step1: Start Step 2: Declare variable Step 3:Assign values to variable Step 4:Declare a function complex Step 5:Defining function with addition Step 6:Function call Step 7:Display sum Step 8:End
