PHP 中四舍五入到最接近的 50,000 [英] Round up to the nearest 50,000 in PHP

问题描述

有没有办法在 PHP 中四舍五入到最接近的 50,000?

Is there a way to round up to the nearest 50,000 in PHP?

我已经调查过了，但文档没有建议这样做的方法，而且看起来好像只是为了向上/向下四舍五入到最近的数字.谢谢.

I've investigated round, but the docs don't suggest a way to do this, and it looks as though it is only for rounding up/down to the nearest numner. Thanks.

推荐答案

/**
 * Round a number up to the nearest multiple of $n.
 *
 * @param int $int  Number to round.
 * @param int $n    Round to the nearest $n.
 *
 * @return int
 */
function round_up_to_nearest_n($int, $n) {
    return ceil($int / $n) * $n;
}
echo round_up_to_nearest_n(74268, 50000); //Outputs 100000

除以要舍入的数字，进行舍入，然后再乘以它.

Divide by the number you want to round against, do the rounding, then multiply by it again.
