  • Last Updated : 07 Jan, 2020

Complex#angle() : angle() is a Complex class method which returns the angle part of the polar form of complex value.

Syntax: Complex.angle()

Parameter: Complex values

Return: angle part of the polar form of complex value.

Example #1 :






# Ruby code for Complex.angle() method
  
# declaring Complex value
a = Complex(200)
  
# declaring Complex value
b = Complex(-1, 4)
  
# declaring Complex value
c = Complex('i')
  
  
# use of angle()  
puts "Complex angle form : #{a.angle}\n\n"
  
puts "Complex angle form : #{b.angle}\n\n"
  
puts "Complex angle form : #{c.angle}\n\n"

Output :

Complex angle form : 0.0

Complex angle form : 1.8157749899217608

Complex angle form : 1.5707963267948966

Example #2 :




# Ruby code for Complex.angle() method
  
# declaring Complex value
a = Complex(20, 90)
  
# declaring Complex value
b = Complex('i')
  
# declaring Complex value
c = Complex(100, -500)
  
# use of angle()  
puts "Complex angle form : #{a.angle}\n\n"
  
puts "Complex angle form : #{b.angle}\n\n"
  
puts "Complex angle form : #{c.angle}\n\n"

Output :

Complex angle form : 1.3521273809209546

Complex angle form : 1.5707963267948966

Complex angle form : -1.373400766945016
