my favorite quote is from the discussion of minus zero: "Signed magnitude...doesn't seem like such a difficult problem today, when hardware is, by the standards of the 1950's when the [UNIVAC] 1100 series was designed, free, but when you put yourself in the place of designers who knew that each logic gate cost several dollars and, in the vacuum tube era, took up substantial space and gave off more heat than an entire computer does today, the need to simplify was compelling.""
