If I remember correctly, it was an error exactly like this that
blew up a U.S. rocket (complete with astronauts) back in the '70s.
One of the programmers used a comma instead of a period, or vice
versa, and no one caught it. The story was related in the C.P.S.R.
paper that argued against the "Star Wars" boondoggle. The paper
even included the original line of code.
