round() function problem

[Anon]

Hello,
Got a problem with teh round() function.
Can someone help?
The following code shows an error

$r=round(3456.225342,2)
echo "r = $r";

: Wrong parameter count for round() in C:[path]\r.php3 on line 3

I'm using PHP 3.16 BTW

Thanks,
red

Guess it's a 3.16 problem, it works fine in 4.0.2.

round function accepts only one parameter

so you can't really write round(3456.225342,2); you must only write(3456.225342);

or try this one:

$r=sprintf("%.2f",3456.225342);

$r = (double)($r);

echo $r;
