Blizzard Entertainment® Announces .999~ (Repeating) = 1

IRVINE, Calif. - APRIL 1, 2004 - At a press conference earlier today, Blizzard Entertainment® announced that .999~ does in fact equal 1. For seven and a half years, enthusiastic forum-goers have fervently debated the issue on the® forums. Does .999~ equal 1? Does .999~ not equal 1? The popular forum topic reached its epic conclusion today, as Blizzard revealed the proof that finally brought an end to the discussion and thus resolved the conundrum that has plagued visitors to the forums for so long.

"We are very excited to close the book on this subject once and for all," stated Mike Morhaime, Blizzard Entertainment president and co-founder. "We've witnessed the heartache and concern over whether .999~ does or does not equal 1, and we're proud that the following proof finally and conclusively addresses the issue for our customers."


lim(m --> ∞) sum(n = 1)^m (9)/(10^n) = 1 
0.9999... = 1
 x = 0.9999... 
10x = 9.9999... 
10x - x = 9.9999... - 0.9999... 
 9x = 9 
 x = 1.

Elaborate and yet crafted with deceptive simplicity and elegance, Blizzard's proof that .999~ = 1 is a true wonder of modern mathematics. More information on how the proof was derived will be revealed in the months ahead. Please stay tuned to for further announcements regarding this and other upcoming proofs from Blizzard Entertainment.
