# Four ways to write complex numbers:
|
|
a = Complex(1, 1) # 1. call Kernel#Complex
|
|
i = Complex::I # 2. use Complex::I
|
|
b = 3.14159 + 1.25 * i
|
|
c = '1/2+3/4i'.to_c # 3. Use the .to_c method from String, result ((1/2)+(3/4)*i)
|
|
c = 1.0/2+3/4i # (0.5-(3/4)*i)
|
|
|
|
# Operations:
|
|
puts a + b # addition
|
|
puts a * b # multiplication
|
|
puts -a # negation
|
|
puts 1.quo a # multiplicative inverse
|
|
puts a.conjugate # complex conjugate
|
|
puts a.conj # alias for complex conjugate
