Ruby | Complex - function Last Updated : 07 Jan, 2020 Comments Improve Suggest changes Like Article Like Report Complex#-() is a Complex class method which performs the subtraction operation on complex numbers. Syntax: Complex.-() Parameter: Complex values Return: subtraction operation on complex numbers. 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') # subtraction puts "Complex - form : #{a-b}\n\n" puts "Complex - form : #{b-c}\n\n" puts "Complex - form : #{c-a}\n\n" Output : Complex - form : 201-4i Complex - form : -1+3i Complex - form : -200+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) # subtraction puts "Complex - form : #{a-b}\n\n" puts "Complex - form : #{b-c}\n\n" puts "Complex - form : #{c-a}\n\n" Output : Complex - form : 20+89i Complex - form : -100+501i Complex - form : 80-590i 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 division value on two complex numbers.
