Complex number

Since a complex number is comprised of a real and imaginary component, two complex numbers are equal if and only if their respective real and imaginary components are equal.

{% highlight swift %} extension Complex: Equatable {}

// MARK: Equatable

func ==(lhs: Complex, rhs: Complex) -> Bool { return lhs.real == rhs.real && lhs.imaginary == rhs.imaginary } {% endhighlight %}
