Re: FLASH: Formatting Numbers, decimals

[Helen Triolo]

Hi Branden.  I think you missed the beginning of this thread, which was:

how would you format a number with commas marking the thousands,

millions, etc (eg, 32549325 -> 32,549,325).  ( My attempt at answering

this is at http://i-technica.com/whitestuff/formatmillions.html )


The followup question was "and what if that number has a decimal?"  (eg,

32593256.43254 -> 32,593,256.43254)  So, a formatting problem rather

than a display-rounded problem, which is what I was trying to address

below.  Your code suggestions welcome of course!
