I wrote a small script to add values in a hash of arrays. Anyway, when numbers like "1483" was added to "-1483.00" I sometimes got an answer like "-9.09494701772928e-13". What?!
I used printf to format the number to "-0.00". Why does perl do this? is there a way for me to make zero be "0"?
Oh, this usually happened on the last iterations of additions.
Thanks
