Rounding an integer to the closest divisor by ten is easy with

Example, round to the closest 5000, or closest 400? Any great
ideas?
Thanks, and merry x-mas!

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!

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...
