红宝石 |复杂的 abs函数

Complex#abs()是一个 Complex 类方法，它返回复数的极坐标形式的绝对值。

Syntax: Complex.abs()

Parameter: Complex values

Return: absolute value of the polar form of complex value.

示例 #1：

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

输出 ：

Complex abs form : 200

Complex abs form : 4.123105625617661

Complex abs form : 1

示例 #2：

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

输出 ：

Complex abs form : 92.19544457292888

Complex abs form : 1

Complex abs form : 509.9019513592785
