Round to nearest whole number

user55

Hi,

I am having trouble figuring out how to do something like this:

For example, lets say the form value of a field was 3,638

Is there some PHP code that will round it to the nearest whole number which would be: 3,500

I guess it would be to the nearest hundred and nearest thousand. I want it to display it only in 500 increments like this:

500
1000
1500
2000
2500
3000
3500 and so on

It wouldn't be just for one, but for multiple random values on several fields. I hope all of this makes sense.

Any help is appreciated. Thanks!

Regards,

Sara

check one of the following ..

float floor ( float value )

float round ( float val [, int precision] )

float ceil ( float value )

Hi Shamly, thanks for the reply. Can you provide a PHP code example, as I am still confused.

To learn about a PHP command, you can usually type the command after the URL like this:

http://www.php.net/ceil
http://www.php.net/round
http://www.php.net/floor

<?php
function roundToInt($value, $int)
{
   $int = (int) $int;
   $value = round($value / $int, 0);
   return(round($value * $int, 0));
}
// sample usage:
$value = 3638;
echo roundToInt($value, 500); // outputs: 3500
?>
