Russel points out that I already had the calculator to do the conversion -- Windows calculator in scientific mode. Cool. So, 270 is 10E hex. What no one seems to know is what the "8-byte binary" part means. This is what 151 looks like in this format, apparently: 97 00 00 00 00 00 00 00. (I sure wish I had that comments feature back, so I could limit talk about such a boring subject [to most people] to a thread! SOON. Hopefully.)
