in reply to Floats with trailing zeros as a hash key

Use printf rather than print to output the hash keys.
printf "%.2f\n", $_ for keys %ITEMS; __OUTPUT__ 58.29 38.55 45.20 29.95

    The prints I had in the example were only that: an example. The real script is accessing the hash based on some user input (with validation, of course), not printing out all the keys just for fun.

    I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

      Then use sprintf? The internal representation of numbers shouldn't really matter - you can always convert them to the right format if needs be.

      If it is important, then initialise them all as strings for consistency, at least.
