asp.net(c#)复数类(复数加减乘除四则运算)
我的一个JAVA作业，把它改写成asp.net(c#)了
复制代码 代码如下:
protected void Page_Load(object sender, EventArgs e) { complex complex_a = new complex(1.0, 1.0); complex complex_b = new complex(2.0, 2.0); Response.Write("加法运算结果：" + complex_a.complex_add(complex_b).ToString() + "<br />"); Response.Write("减法运算结果：" + complex_a.complex_minus(complex_b).ToString() + "<br />"); Response.Write("乘法运算结果：" + complex_a.complex_multi(complex_b).ToString() + "<br />"); Response.Write("除法运算结果：" + complex_a.complex_divide(complex_b).ToString()); } //design by 阿会楠 来自：搜索吧 sosuo8.com public class complex { //复数中的实部 private double complex_real; //复数中的虚部 private double complex_imagin; //构造函数 public complex(double r, double i) { complex_real = r; complex_imagin = i; } //重写ToString()方法 public override string ToString() { return this.complex_real + "+" + this.complex_imagin + "i"; } //复数加法运算 public complex complex_add(complex c) { //取得加法运算后的实部 double complex_real = this.complex_real + c.complex_real; //取得加法运算后的虚部 double complex_imagin = this.complex_imagin + c.complex_imagin; //返回一个复数类 return new complex(complex_real,complex_imagin); } //复数减法运算 public complex complex_minus(complex c) { //取得减法运算后的实部 double complex_real = this.complex_real - c.complex_real; //取得减法运算后的虚部 double complex_imagin = this.complex_imagin - c.complex_imagin; //返回一个复数类 return new complex(complex_real, complex_imagin); } //乘法运算 public complex complex_multi(complex c) { //取得乘法运算后的实部 double complex_real = this.complex_real * c.complex_real - this.complex_imagin * c.complex_imagin; //取得乘法运算后的虚部 double complex_imagin = this.complex_real * c.complex_imagin + this.complex_imagin * c.complex_real; //返回一个复数类 return new complex(complex_real, complex_imagin); } //除法运算结果 (a+bi)/(c+di)=(a+bi)(c-di)/(c+di)(c-di) public complex complex_divide(complex c) { //取得(c+di)(c-di)的值 double d = c.complex_real * c.complex_real + c.complex_imagin * c.complex_imagin; //取得除法运算后的实部 double complex_real = (this.complex_real * c.complex_real + this.complex_imagin * c.complex_imagin) / d; //取得除法运算后的虚部 double complex_imagin = (this.complex_real * (-c.complex_imagin) + this.complex_imagin * c.complex_real) / d; //返回一个复数类 return new complex(complex_real, complex_imagin); } }
运行结果：
复制代码 代码如下:
加法运算结果：3+3i 减法运算结果：-1+-1i 乘法运算结果：0+4i 除法运算结果：0.5+0i
