Complex#+@():+@() 是一個 Complex 類方法,它返回複數值的正值,即 a = +(a)
用法:Complex.+()
參數:複數值
Return: 複數值的正值。
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')
# positive value
puts "Complex + form : #{+a}\n\n"
puts "Complex + form : #{+b}\n\n"
puts "Complex + form : #{+c}\n\n"
輸出:
Complex + form : -200+800i Complex + form : -4-1i Complex + form : 0+200i
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)
# positive value
puts "Complex + form : #{+a}\n\n"
puts "Complex + form : #{+b}\n\n"
puts "Complex + form : #{+c}\n\n"
輸出:
Complex + form : 20+90i Complex + form : 0+1i Complex + form : 100-500i
