click house 数据库的intDiv函数计算原理

select intDiv(500000,50); --10000
select intDiv(500001,50); --10000
select intDiv(500050,50); --10001

Java代码实现

public static int intDiv(int a, int b) {
    if (b != 0) {
        return a / b;
    } else {
        throw new ArithmeticException("Division by zero is not allowed.");
    }
}

public static void main(S服务器托管网tring[] args) {
    int a = 500000;
    int b = 50;
    System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b));

    a = 500001;
    b = 50;
    System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b));

    a = 500050;
    b = 50;
    System.out.println("Result of intDiv(" + a + ", " + b + "): " + intDiv(a, b)服务器托管网);
}

输出结果

Result of intDiv(500000, 50): 10000
Result of intDiv(500001, 50): 10000
Result of intDiv(500050, 50): 10001
