Swift使用笛卡尔和极坐标进行转换的复数计算器

import Foundation
struct Complex{
//实部real
public var real : Double = 0
//虚部img
public var img : Double = 0
public var polar :(mod:Double,arg:Double) = (0,0)
public var Cartesian :(real:Double,img:Double) = (0,0)
public var FirstPolar :(mod:Double,arg:Double) = (0,0)
init(PolarNumber:(mod:Double,arg:Double)) {
FirstPolar = PolarNumber
ChangePolar = PolarNumber as (Double,Double)
// print(judgment(parameter: ChangePolar))
}
//笛卡尔转极坐标
public var ChangeCartesian :(mod:Double,arg:Double){
get{
return polar
}
set(CartesianNum){
polar.mod = sqrt((CartesianNum.mod * CartesianNum.mod)+(CartesianNum.arg * CartesianNum.arg))
polar.arg = atan2(CartesianNum.arg, CartesianNum.mod)
}
}
//极坐标转笛卡尔
public var ChangePolar : (real:Double,img:Double){
get{
return Cartesian
}
set(PolarNum){
Cartesian.real = PolarNum.real * cos(PolarNum.img)
Cartesian.img = PolarNum.real * sin(PolarNum.img)
}
}
//判断
public func judgment(parameter:(real:Double,img:Double))->String {
if parameter.img > 0 {
return "\(Double(round(parameter.real * 1000)/1000))+\(Double(round(parameter.img * 1000)/1000))i"
} else if parameter.img < 0 {
return "\(Double(round(parameter.real * 1000)/1000))-\(-(Double(round(parameter.img * 1000)/1000)))i"
} else {
return "\(Double(round(parameter.img * 1000)/1000))"
}
}
//计算前进行格式转换
public mutating func ChangeAdd(AddNum:(mod:Double,arg:Double)){
ChangePolar = FirstPolar as (Double,Double)
//初始值通过set进行了转换
let x = ChangePolar
//用x进行一个存储
ChangePolar = AddNum as (Double,Double)
let y = ChangePolar
Add(x: x, y: y)
//调用Add方法，进行运算
}
public mutating func ChangeSubtract(SubNum:(mod:Double,arg:Double)){
ChangePolar = FirstPolar as (Double,Double)
let x = ChangePolar
ChangePolar = SubNum as (Double,Double)
let y = ChangePolar
Subtract(x: x, y: y)
}
public mutating func ChangeMultiply(MulNum:(mod:Double,arg:Double)){
ChangePolar = FirstPolar as (Double,Double)
let x = ChangePolar
ChangePolar = MulNum as (Double,Double)
let y = ChangePolar
Multiply(x: x, y: y)
}
public mutating func ChangeDiv(DivNum:(mod:Double,arg:Double)){
Divide(x: FirstPolar, y: DivNum)
}
//加减乘除方法
public func Add(x:(real:Double,img:Double),y:(real:Double,img:Double)){
let answer = (x.real + y.real,x.img + y.img)
print(judgment(parameter: answer))
}
public func Subtract(x:(real:Double,img:Double),y:(real:Double,img:Double)){
let answer = (x.real - y.real,x.img - y.img)
print(judgment(parameter: answer))
}
public func Multiply(x:(real:Double,img:Double),y:(real:Double,img:Double)){
let answer = (x.real * y.real - x.img * y.img,x.real * y.real + x.img * y.img)
print(judgment(parameter: answer))
}
public mutating func Divide(x:(mod:Double,arg:Double),y:(mod:Double,arg:Double)){
let answer = ((x.mod / y.mod),(x.arg - y.arg))
// ChangePolar = answer
