Limit Decimal Digits?

[universelittle]

Hello,
Is there any PHP function that can limit the decimal digits?
If I got a double number like 5.123456, too many decimal digits,
how to limit it to 5.12?
Thanks!

function chrisarms($value) {
if(!ereg(".",$value) {
return($value);
}
$parts = explode(".",$value);
$afterpoint = substr($parts[1],0,2);
$everything = $parts[0].".".$afterpoint;
return($everything);
}

number_format() being the easy way 🙂

<?
$number = 5.123456;
$format_num = number_format($number, 2);
?>

There again,

$conversion=92.663532
$formatted = sprintf("%01.2f", $conversion);
echo $formatted;

Could also be anothe way of putting it.
