There is a factory constructor: Complex.ofReal(double)
For completeness I think we should add: Complex.ofImaginary(double) We also have negate() as a helper. I think the following are also useful: Complex multiplyI() Complex multiplyNegativeI() These two operations appear a lot in the formulas for the trigonomic functions. They essentially just swap the real and imaginary parts and update the sign appropriately.
