Ruby | Complex angle function

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
