Usage
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))
