Actually if you do it that way it'll slow the process down by about
700% since it has to do all the mathematical conversion. My way
involves no real mathetical conversion at all and simple tags the
needed numbers with an extra zero if necesary.
Obviously Bumbles didn't actually test this stupidity, he just slurped
it up from some halfassed Google hump and thought he'd try and play
Flash Professor...sorry Bumbles, but ya get to look stupid ALL over
again. Oh hey, do something stupid like reply this post with a lil
fit throwing, maybe I'll decide to further humiliate you with a little
side by side video comparison of the two methods, just to further beat
you with your own stupidity. ^_^
