[ILUG] OT: Formatting Perl output on Web Page?

[Cormac McClean]

Hi,

This is probably a RTFM question, and I am checking, but no joy.
I also have 2 books on Perl but I loaned these and am (temporarily)
bereft of their wisdom. (Question is possibly also OT).

I am using Perl and Apache on Linux to read data from text files and
output the data into a HTML table. (Next step will be to use MySQL
to store the data). My question is this: how do I curtail the amount
of decimals being displayed from a decimal scalar, e.g. to get the 
percentage attendance based on classess attened / total classes * 100:
	$att_pc = $att / $total * 100;
when I display this using a print statement I get 12 decimal places,
which looks a bit silly:
	print "<TD align=center>$att_pc</TD>";

Is there a Perl equivalent to the C %.2f to format output to 2 decimal 
places?

Apologies for the OT nature of this question.

Regards,
Cormac.
