Here's another way to approach it: 

sub trunc {
    my ($float, $precision) = @_[0..1];
    my @comp = split /\./, $float;
    
    chop $comp[1] while length($comp[1]) > $precision; #trim
    $comp[1].='0' for (length($comp[1])..$precision-1);  #pad
    
    return "$comp[0].$comp[1]";
}

printf ("%5.2f", trunc($yearlyamount/52,2));

This will, of course, fail utterly if you pass in anything less than pristine values. I leave data validation and error handling as an exercise to whatever masochist chooses this route. Of course, you could also implement it in this insane manner: 

$weekly = int(($yearlyamount/52)*100);
$weekly = s,\d{2}$,\.$&,;
printf ("%5.2f", $weekly);

As a last resort, you could always: 

$weekly = sprintf("%.3", $yearlyamount/52);
chop($weekly);
printf "%5.2", $weekly;
