Math Question....
in [General]
|
From: Dan Joseph on 22 Apr 2010 10:07 Howdy, This is a math question, but I'm doing the code in PHP, and have expunged all resources... hoping someone can guide me here. For some reason, I can't figure this out. I want to take a group of items, and divide them into equal groups based on a max per group. Example. 1,252,398 -- divide into equal groups with only 30 items per group max. Can anyone guide me towards an algorithm or formula name to solve this? PHP code or Math stuff is fine. Either way...

Which is where I come to looking for a the right method to break it equally. -- -Dan Joseph www.canishosting.com - Unlimited Hosting Plans start @ $3.95/month.

If the number doesn't fit, then you've got a remainder, and no math is going to change that. How do you want that remainder distributed? Thanks, Ash http://www.ashleysheridan.co.uk
From: "Jo�o C�ndido de Souza Neto" on 22 Apr 2010 10:24 for ($g = $maxpergroup; $g > 0; $g++) { if ($items mod $g <> 0) continue; $Groups = $items div $g; } Maybe it can helps you.
