What if you want to chop a number but not round it? printf just *wants* to round, no option to tell it not to :(

I needed something that would chop the extra digits (price calculataions) without rounding.

quick fox was to compare the sprintf result with the original and if it was larger remove 0.01 - yuk!...

I ended up using split and substr... - not pretty either

There must be a better way!

[perldigious]: Quick question, is undef %hash a recommended/good way to delete an entire hash structure from memory? Or sould I be doing it some other way?
[1nickt]: The best way is to scope it tightly so it just goes away when you are finished with it.
[perldigious]: but... but... perldigious is the unvirtuous kind of lazy in this case. :-)
[perldigious]: Just kidding. Thanks 1nickt, I'll go ahead and do it the right way. An extra set of brackets and a little extra indentation isn't too much to ask.
[karlgoethebier]: perldigious: perhaps a block if you are paranoid ;-)
