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

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
