formatting numerical output

bilbozilla has asked for the wisdom of the Perl Monks concerning the following question:

I need some help with this one. I have the data and I want it formatted to carry the number out to 2 decimal places. Here is the code:

my ( $wantedx, $wantedy ) = ( $wanted =~ /($decimal).*?($decimal)/ );

Could you please assist me on this one?

`my $blah = sprintf("%.2f", 3.1415926535); print "$blah\n"; __END__ prints 3.14` [download] Keep in mind this doesn't round, only truncates decimals. If you want the result in two different variables (for the stuff before and after the decimal), split on `/\./` blokhead	[reply] [d/l] [select]
