Question

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

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.

Answer 1

/**
 * 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

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