如何在Java中舍入整数除法并得到int结果？

要舍入整数除法，您可以使用

import static java.lang.Math.abs;public static long roundUp(long num, long divisor) {    int sign = (num > 0 ? 1 : -1) * (divisor > 0 ? 1 : -1);    return sign * (abs(num) + abs(divisor) - 1) / abs(divisor);}

或者两个数字都为正

public static long roundUp(long num, long divisor) {    return (num + divisor - 1) / divisor;}
