Monks,

I am looking for a graceful way to round numbers.

The following program
#!/bin/perl

sub myround
{
   my $src = shift;
   printf("%.2f\n", $src);
}

myround("1.335");
myround("0.335");

outputs this:
$ perl ./round.pl
1.33
0.34

I know why.  It has to do with the well known side effects of using
floating point.

What I don't know is a graceful way to round.

I would like to use something that already comes with perl and void
adding any modules.
