Ruby | Complex arg() method

Last Updated : 07 Jan, 2020

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 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 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
