Decimal

[Anon]

If I have a number like: 654.3213213215, i need to get on the number before the decimal, and the 2 digits after it. Any ideas?

something like this maybe:

$d = 654.3213213215;
$d = preg_replace( "/(.\d{2})\d+/", "\1" , $d );

Hi!

Try round() function!

$foo=round(654.3213213215,2);

and you'll get 2 digits after the decimal.

<?php
$r=round(3456.225342,2);
echo "rr $r";
?>
returns an error
Warning: Wrong parameter count for round() in C:[path]\r.php3 on line 3

Does anyone have an answer for this ?

Thanks,
