Hi, I figured this would be a good place to get the answer to my question. I need help with decoding the 4 O'clock position of this geek watch (see attachment). It reads [pi] (???). If someone could tell me what is this referring to. Thank you very much. FMT

Well, slap my knee, but somehow [pi] = 4 Only way I can see this is [] means floor function floor(pi) = 4 (4) = 4 I rest my case... Watch Repair Shop slogan: "If your watch don't tick, tock to us"

Indeed. When you have mathematical typesetting it should be written but when you just have ASCII [pi] is fine. By now I think everyone has realized that gives for positive x.
