Complex#angle():angle()是Complex类方法,它返回复数值的极坐标形式的角部分。
用法:Complex.angle()
参数:复数值
返回:极角部分的复数形式。
示例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"
输出:
Complex angle form : 0.0 Complex angle form : 1.8157749899217608 Complex angle form : 1.5707963267948966
示例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"
输出:
Complex angle form : 1.3521273809209546 Complex angle form : 1.5707963267948966 Complex angle form : -1.373400766945016
