If you don't mind predefining your keys:
my $key1 = sprintf "%.2f", 45.20;
my %ITEMS = ( $key1 => 'item 1');

This will work. I tested it as follows: 
$key1 = sprintf "%.2f", 52.30;
my %ITEMS = (
    $key1 => 'item 1',
    45.25 => 'item 2'
);
my $input = <STDIN>;
chomp ($input);
if (exists $ITEMS{$input}) {
    print $ITEMS{$input} . "\n";
}

It printed "item 1" when I entered 52.30.
