java double 加减乘除

在Java中，`double`类型用于表示双精度浮点数。以下是一些关于`double`类型的基本操作，包括加、减、乘、除：

### 加法

double a = 10.5;
double b = 5.2;
double sum = a + b; // 结果为 15.7
System.out.println("Sum: " + sum);

### 减法

double a = 10.5;
double b = 5.2;
double difference = a - b; // 结果为 5.3
System.out.println("Difference: " + difference);

### 乘法

double a = 10.5;
double b = 5.2;
double product = a * b; // 结果为 54.6
System.out.println("Product: " + product);

### 除法

double a = 10.5;
double b = 5.2;
double quotient = a / b; // 结果为 2.019230769230769
System.out.println("Quotient: " + quotient);

### 示例代码

public class DoubleOperations {
    public static void main(String[] args) {
        double a = 10.5;
        double b = 5.2;

        double sum = a + b;
        double difference = a - b;
        double product = a * b;
        double quotient = a / b;

        System.out.println("Sum: " + sum);
        System.out.println("Difference: " + difference);
        System.out.println("Product: " + product);
        System.out.println("Quotient: " + quotient);
    }
}

运行上述代码将输出：

Sum: 15.7
Difference: 5.3
Product: 54.6
Quotient: 2.019230769230769
