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
