Hi,
Is there a way to round down to the nearest 50? Example: Any number between 400 and 449 I would 400 to be displayed; 450 to 499 would be 450; 500 to 549 would be 500, etc?
Off the top of my head: divide the number by 50, run floor() on the result, then times it by 50. 1. 449 / 50 = 9.whatever 2. floor(9.whatever) = 9 3. 9 * 50 = 450 -- Richard Heyes HTML5 graphing: RGraph - www.rgraph.net (updated 8th August) Lots of PHP and Javascript code - http://www.phpguru.org
It should be round() and not floor(). 449 / 50 = 8.98 floor(8.98) = 8 8 * 50 = 400 round(8.98) = 9 9 * 50 = 450 Thanks, Ash http://www.ashleysheridan.co.uk
