Round Question

[jester626]

I am pulling info from a MySQL DB.

When I go to use Round like this:

 

echo round($containers,1);

 

It will give me an answer of 5.1 which is mathematically correct. However, I want it to give me an answer to the next highest half (.5) of a container so in this instance I would want the answer of 5.5 not 5.1.  Is there a way to round to the next highest half?

 

Thanks in advance

If I understand correctly this is what you want:

Input > Output

5.0 > 5.0

5.1 > 5.5

5.2 > 5.5

5.3 > 5.5

5.4 > 5.5

5.5 > 5.5

5.6 > 6

5.7 > 6

5.8 > 6

5.9 > 6

6.0 > 6

 

Than this will do the trick:

<?php
$input = 5.1;
$output = ceil($input * 2) / 2;
echo $output;
?>
