Removing trailing zero's from decimal

Question

Hi i was wondering how i could remove the last 2 zero's as seen below:

13.6500
16.0000
17.5345

To the following:

13.65
16.00
17.5345

use `round($input,2)` to round to two decimals – krishna May 12 '14 at 10:01 — krishna, May 12 '14 at 10:01
`number_format($number, 2);` – CodeBird May 12 '14 at 10:02 — CodeBird, May 12 '14 at 10:02

You can use round() like this to round to 2 decimal points like this

echo round("13.6500",2);

Also you can use number_format() like this

echo number_format("13.6500", 2);

Both yeilds the O/P

13.65

EDIT

from the comment i think what you want is like this

$input = "12.00000";

$length = strlen(substr(strrchr($input, "."), 1));

if($length > 2)
{
    $input =$input+0;
    if(strlen(substr(strrchr($input, "."), 1)) < 1)
    {
        $input = $input.".00";
    }
    else if(strlen(substr(strrchr($input, "."), 1)) < 2)
    {
         $input = $input.".0";
    }
    echo $input;
}
else
{
    echo $input;
}

Thanks for your response but i forgot to mention that it shouldnt round the decimal incase there are more then 4. – user3600204 May 12 '14 at 10:41
@user3600204 can you give examples ? – krishna May 12 '14 at 10:42
@user3600204 how `17.5345` remains the same ? – krishna May 12 '14 at 10:55
17.5345 should remain the same but if there are zero's after the first 2 decimals they should be removed. Also the edited part doesnt seem to work :( – user3600204 May 12 '14 at 11:07
