Question

I am not used to Complex class in Ruby. I read the doc but I cannot figure how to modify the real or imaginary part of such a complex number. The accessor to modify these fields is not provided.

c=Complex(1,2)
c.real= 4 # impossible as is

So my question is : how to modify the real or imaginary part of a complex number in Ruby ?

I particulary think a solution based on open class should be possible ?

Answer 1

You will have to create a new complex number:

c = Complex(1, 2)
c = Complex(2, c.imag)
