Re: 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

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. -- Schemer Note: All code is untested, unless otherwise stated	[reply]

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.	[reply]
