Complex

case class Complex(re: Double, im: Double = 0.0) extends Fractional[Complex] with Ordered[Complex] with Product with Serializable

The Complex class is used to represent and operate on complex numbers. Internally, a complex number is represented as two double precision floating point numbers (Double). Externally, two forms are supported:

a+bi = 2.1+3.2i via: Complex ("2.1+3.2i"), toString (a, b) = (2.1, 3.2) via: create ("(2.1,=, 3.2)"), toString2

Note: 'i * i = -1'.

re

the real part (e.g., 2.1)

im

the imaginary part (e.g., 3.2)
