(Senary isn't either, but it represents 1/5 a lot nicer than duodecimal does). Reason two, it has a low radix economy. Reason three, it is the best finger-counting base. All numbers from 0-35 can be represented on just two hands.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-24979544045701706492018-05-05T13:28:21.965-04:002018-05-05T13:28:21.965-04:00Base 9Base 9Andyhttps://www.blogger.com/profile/05494055326933615807noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-57011825670420239082018-05-05T13:23:22.803-04:002018-05-05T13:23:22.803-04:00Base 9 the trig divisible functions representative...Base 9 the trig divisible functions representative as multiplesAndyhttps://www.blogger.com/profile/05494055326933615807noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-17123864937432215252018-05-05T13:23:20.513-04:002018-05-05T13:23:20.513-04:00Base 9 the trig divisible functions representative...Base 9 the trig divisible functions representative as multiplesAndyhttps://www.blogger.com/profile/05494055326933615807noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-58909673130095092902017-11-20T20:40:26.658-05:002017-11-20T20:40:26.658-05:001 hour to be comprised of 100 minutes is already a...1 hour to be comprised of 100 minutes is already a tried and given up amendment during the French Revolution.Mugdha Thakurhttps://www.blogger.com/profile/11876864940789829988noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-44017562223336941342017-08-29T05:29:26.679-04:002017-08-29T05:29:26.679-04:00Only good in some theoretical situations, but is l...Only good in some theoretical situations, but is largely impractical both for mathematics and computers.

This is why traditional weights and measures use base 12. The problem has always been with using base 10 to count.<br /><br />For those complaining about the need to invent to additional symbols, I would suggest base 6 as an alternative.

Wit...Base two has a huge problem for us humanoids. Without training we have about a 7 digit short-term memory. This severely limits the largest number that we can work with in mental math. This excludes binary for most uses, but a binary based numbering would be excellent: 4, 8, 16. Probably the easiest to change to would be hex, because it is big enough to overcome many memory problems, and it is in common use in some segments of society (nerds).<BR/><BR/>If we had enough digits, I would vote for base 72, it claims as factors, 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72. It is probably the most densely divisible number under 100. Its biggest drawback is that it is not binary based.tobiwannoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-90932976211660148952008-04-30T21:00:00.000-04:002008-04-30T21:00:00.000-04:00Bigendian is a must.
