Calculation and limiting decimals

[Jay2391]

Example:

 

I have a greater total of 61 and I score 45

 

$i= 61;

$y= 45;

 

 

$pct = ($i /$y) * 100;

 

one is tha correct ??? Two how can i limit the number that result diplays (0.987654321 - i just want .987)

 

and how do i turn off this error message???

 

Warning: Division by zero in localhost\info.php on line xxx

<?php
$i = 61;
$y = 45;

$pct = ($i/$y) * 100;

echo "Before round: " . $pct . "<br />\n";
echo "After round: " . round($pct,3);
?>

 

Before round: 135.555555556
After round: 135.556

And to remove any error messages you may encounter put:

<?php 
ini_set('display_errors', False);
//code...
?>

(on the first line after your <?php tag)

substr() function I believe might work.
