Objective-C实现复数类+-x

一个简洁的Objective-C复数类实现

在软件开发中，复数运算是一个常见需求。Objective-C作为一门灵活强大的编程语言，拥有丰富的类和方法，能够轻松支持复数运算。以下是一个简洁的Objective-C实现复数类的代码示例，支持加法、减法、乘法、除法和取模运算。

类结构

#import 
   
    @interface Complex : NSObject {    double _real;    double _imaginary;}@property (nonatomic, assign) double real;@property (nonatomic, assign) double imaginary;@end
   

实现细节

属性声明

@interface Complex : NSObject {    double _real;    double _imaginary;}@property (nonatomic, assign) double real;@property (nonatomic, assign) double imaginary;@end

初始化方法

-(id)initWithReal:(double)real withImaginary:(double)imaginary {    self.real = real;    self.imaginary = imaginary;    return self;}

加法运算

-(Complex *)add:(Complex *)other {    Complex *result = [[Complex alloc] init];    result.real = self.real + other.real;    result.imaginary = self.imaginary + other.imaginary;    return result;}

减法运算

-(Complex *)subtract:(Complex *)other {    Complex *result = [[Complex alloc] init];    result.real = self.real - other.real;    result.imaginary = self.imaginary - other.imaginary;    return result;}

乘法运算

-(Complex *)multiply:(Complex *)other {    Complex *result = [[Complex alloc] init];    result.real = self.real * other.real - self.imaginary * other.imaginary;    result.imaginary = self.real * other.imaginary + self.imaginary * other.real;    return result;}

除法运算

-(Complex *)divide:(Complex *)other {    Complex *result = [[Complex alloc] init];    double divisor = other.real * other.real + other.imaginary * other.imaginary;    if (divisor != 0) {        result.real = (self.real * other.real + self.imaginary * other.imaginary) / divisor;        result.imaginary = (self.imaginary * other.real - self.real * other.imaginary) / divisor;    } else {        result.real = 0;        result.imaginary = 0;    }    return result;}

取模运算

-(Complex *)modulo:(Complex *)other {    Complex *result = [[Complex alloc] init];    double divisor = other.real * other.real + other.imaginary * other.imaginary;    if (divisor != 0) {        result.real = (self.real * other.real + self.imaginary * other.imaginary) / divisor;        result.imaginary = (self.imaginary * other.real - self.real * other.imaginary) / divisor;    } else {        result.real = 0;        result.imaginary = 0;    }    return result;}

优势与应用

这个复数类实现了基本的复数运算，适用于需要处理复数的场景，如工程力学、电路设计、科学计算等。代码结构清晰，方法简洁，易于扩展和维护。

如果需要更高级的功能，如复数的共轭、极坐标形式转换等，可以根据实际需求进行扩展。
