Rounding digits

[Brian]

How can I take a number like say 100.3333444 and round that off to 2 digits so it would output say 100.33 instead.

Thanks in advanced

number_format()

and sprintf (my preference)

Thanks guys unfortunately my php knowledge is slim at best and I cant figure out how to use these

Here is the part of code I need it for:

<? echo $totalvalue; ?>

So basically that value which is printed out (say it would be 141.55221) I would need to be formated to 2 decimal places to say 141.55.

Can you tell me how to do that code wise (sorry for the dumb question I am sloooowly learning lol)

echo sprintf('%.2f', $totalvalue);
