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
