Thanks, and merry x-mas! Anders.

http://www.alixaxel.com/wordpress/wp-content/2008/05/Round.php Someone was way ahead of you and found the answer and posted on the

PHP

manual pages back in May. The manual pages are always useful, even

if

only for the user-written functions! Ash www.ashleysheridan.co.uk

Thanks Ash. I browse the pages frequently for ideas, and also did it yesterday.. However, I must have missed that post, maybe because it was so small

in

the list.. ;-) Thanks for the tip! Anders.

I cheered too fast.. That function rounds to the closest 500, literally.. So, 1100 is rounded to 1500, not to 1000 which would be the correct value. Any more ideas from anyone? My mind isn't working right at the moment, so a "ready-to-plug-in" function would be really great!

Dear Lord.. It seems like it was so much simpler than I would even guess.. Maybe that's why I didn't see it? function roundto($number, $to) { return round($number / $to) * $to; } Anders.

Isn't what you wrote the same as the following? function Multiple($number, $multiple) {

    return round($number / $multiple) * $multiple;

} The above was on the page that Ash linked to... Named differently true, but it was right there in front of you...
