Ruby | Complex arg() method Last Updated : 07 Jan, 2020 Summarize Comments Improve Suggest changes Share Like Article Like Report Complex#arg() is a Complex class method which returns the angle part of the polar form of complex value. Syntax: Complex.arg() Parameter: Complex values Return: angle part of the polar form of complex value. Example #1 : Ruby # Ruby code for Complex.arg() method # declaring Complex value a = Complex(200) # declaring Complex value b = Complex(-1, 4) # declaring Complex value c = Complex('i') # use of arg() puts "Complex arg form : #{a.arg}\n\n" puts "Complex arg form : #{b.arg}\n\n" puts "Complex arg form : #{c.arg}\n\n" Output : Complex arg form : 0.0 Complex arg form : 1.8157749899217608 Complex arg form : 1.5707963267948966 Example #2 : Ruby # Ruby code for Complex.arg() method # declaring Complex value a = Complex(20, 90) # declaring Complex value b = Complex('i') # declaring Complex value c = Complex(100, -500) # use of arg() puts "Complex arg form : #{a.arg}\n\n" puts "Complex arg form : #{b.arg}\n\n" puts "Complex arg form : #{c.arg}\n\n" Output : Complex arg form : 1.3521273809209546 Complex arg form : 1.5707963267948966 Complex arg form : -1.373400766945016 Comment More infoAdvertise with us Next Article Ruby | Complex * method K Kirti_Mangal Follow Improve Article Tags : Ruby Ruby-Methods Ruby Complex-class Similar Reads Ruby | Complex * method Complex#*() is a Complex class method which returns the multiplicative product of two complex values.
