Removing insignificant decimal characters? [message #169479]

I have the following little routing to reduce large numbers into more
comprehensible human-readable values.

What I would like is for some smarts, to not append the decimal or
trailing zeroes in the decimal positions if those are not significant.

eg. I'd like the function to print

300 bytes iso 300.00 bytes

and

4 Kb iso 4.00 Kb.

Any hints as to how I can do this?

Oh, and any comments on coding is appreciated, I'm learning this stuff
and criticism helps. :)

thanks
MikeB

<?php
$mfs = 4096;

echo " Say 4 Kb: " . return_sized($mfs);
echo " Say 300 bytes: " . return_sized(300);
echo " Say 5,000 bytes: " . return_sized(5000);
echo " Say 5,000,000 bytes: " . return_sized(5000000);
echo " Say 5,000,000,000 bytes: " . return_sized(5000000000);
echo " Say 5,000,000,000,000 bytes: " . return_sized(5000000000000);

function return_sized($val) {
/*
* return a large number in more human-readable format
*/
$suffix = array('bytes', ' Kb', ' Mb', ' Gb');
for ($i = 0; $i < 3; ++$i) {
if ($val > 1024) {
$val /= 1024;
} else
break;
};
$val = sprintf("%.2f",$val);
// echo " Function suffix value is $i ";
$val .= $suffix[$i];
// echo ' $val has value: ' . $val ." " ;
return $val;
}

?>
