Imagine

⚡️ A Toy Complex Number Library in Javascript ⚡️

Features

• Complex Numbers!!!i!!!i!!!i!!!!
• Addition, Subtraction
• Multiplication, Division
• Square Roots
• Absolute Values
• A lovely formatted toString() method

Usage

Install it first:

$ npm install --save imaginejs

Now you can use the library

const complex = require('imaginejs');

// Make a new Complex number, 4 + 2i
const num = complex(4, 2)

// Add another complex Number
const newNum = num.add(complex(6,3)) // returns 10 + 5i

// Test some Equality
newNum.equals(num) // False

// find the absolute value and print
console.log(newNum.abs().toString) // "10 + 5i"

// Do a random sum
complex.multiply(Complex(21, 4), Complex(76, 2)) // returns 1588 + 346i

All methods require a complex object to be used, and the library includes the following methods:

• abs()
• add(y)
• subtract(y)
• multiply(y)
• divide(y)
• sqrt()
• toString
• equals(x)

The methods can be used on the complex object like Complex(3, 2).abs() or as static methods, Complex.abs(Complex(3, 2))

Tests

Even though this is a toy library, its all tested! (Cause thats whats good)
