Jim, I concur with you. I have worked with people in the computer business who could do mental arithmetic in hexadecimal just as easily as most of us do it in base 10.

'Nightmaring' would be much more like it!... :-( Looks like one >keeps forgetting that it would take a lot more than just 12 fingers to >make us "comfortable" in the base-12! (Our brains! For some reason, they >simply do NOT work well in any other base but *pure* decimal! God >certainly knew what He was doing... ;-) ) Sorry, Marcus, but there is NOTHING magic about the number 10. If we had grown up with 12 fingers, and had a numbering system based on 12 (e.g., extracting from hexadecimal: 0, 1,2, 3, 4, 5, 6, 7, 8, 9, A, B, 10, 11...), it would appear every bit as "natural" as decimal does to us now. Our brains would be very comfortable with it, and using an "odd" number like 10 for a base would seem weird and uncomfortable. Imagine someone used to base-12, where 1/3 = 0.4. Then you tell him that in decimal 1/3 = 0.33333..... and he would say "What a crummy system!!!" For those of us who have spent years working in binary, octal and hexadecimal, this is pretty obvious. "10" is special through familiarity, not due to anything else. Jim Elwell, CAMS Electrical Engineer Industrial manufacturing manager Salt Lake City, Utah, USA www.qsicorp.com
