Complex#-() 是一個 Complex 類方法,用於對複數執行減法運算。
用法:Complex.-()
參數:複數值
Return: 複數的減法運算。
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"
輸出:
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"
輸出:
Complex - form : 20+89i Complex - form : -100+501i Complex - form : 80-590i
