红宝石 |复杂 -函数

Complex#-()是一个 Complex 类方法，它对复数执行减法运算。

Syntax: Complex.-()

Parameter: Complex values

Return: subtraction operation on complex numbers.

示例 #1：

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

输出 ：

Complex - form : 201-4i

Complex - form : -1+3i

Complex - form : -200+1i

示例 #2：

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

输出 ：

Complex - form : 20+89i

Complex - form : -100+501i

Complex - form : 80-590i
