Syntax: Complex.-@() Parameter: Complex values Return: negation of complex values. Example #1 : Ruby # Ruby code for Complex.-@() method # declaring Complex value a = Complex(200) # declaring Complex value b = Complex(-1, 4) # declaring Complex value c = Complex('i') # negation puts "Complex -@ form : #{-a}\n\n" puts "Complex -@ form : #{-b}\n\n" puts "Complex -@ form : #{-c}\n\n" Output : Complex -@ form : -200+0i Complex -@ form : 1-4i Complex -@ form : 0-1i Example #2 : Ruby # Ruby code for Complex.-@() method # declaring Complex value a = Complex(20, 90) # declaring Complex value b = Complex('i') # declaring Complex value c = Complex(100, -500) # negation puts "Complex -@ form : #{-a}\n\n" puts "Complex -@ form : #{-b}\n\n" puts "Complex -@ form : #{-c}\n\n" Output : Complex -@ form : -20-90i Complex -@ form : 0-1i Complex -@ form : -100+500i Comment More infoAdvertise with us Next Article Ruby | Complex -@ function K Kirti_Mangal Follow Improve Article Tags : Ruby Ruby-Methods Ruby Complex-class Similar Reads Ruby | Complex + function Complex#+@() : +@() is a Complex class method which returns the positive value for a complex value i.e. a = +(a) Syntax: Complex.+() Parameter: Complex values Return: positive value for a complex value.
