i'm thinking about changing CT forms to base 36

That... would be tricky.

I don't think I could ever do intuitive hex arithmetic. What about multiplication? Arriving at 0xa * 0xb = 0x6e in my head was rather tricky involving long division. (I'm not even sure if that's right.)

Long division? Forget decimal. But the answer is correct.

How about B0A * EBD = A2B262? I must admit that took me a while, but I did it all in my head.

I'm not going to even try and work out if that's right.

If you'd change the number of registered users to hex now it'd look like it's only been permuted (2083 => [0]823).

That's... Paying a lot more attention to it than I am.

Nah, just coincidence. I happened to convert it to hex (in my head, of course) at just the right time.

Wrote a little program that checked how many there actually are (<0x10000):

Code: Select all

0 <=> 0x0
1 <=> 0x1
2 <=> 0x2
3 <=> 0x3
4 <=> 0x4
5 <=> 0x5
6 <=> 0x6
7 <=> 0x7
8 <=> 0x8
9 <=> 0x9
53 <=> 0x35
371 <=> 0x173
913 <=> 0x391
1040 <=> 0x410
1041 <=> 0x411
1042 <=> 0x412
1043 <=> 0x413
1044 <=> 0x414
1045 <=> 0x415
1046 <=> 0x416
1047 <=> 0x417
1048 <=> 0x418
1049 <=> 0x419
2080 <=> 0x820
2081 <=> 0x821
2082 <=> 0x822
2083 <=> 0x823
2084 <=> 0x824
2085 <=> 0x825
2086 <=> 0x826
2087 <=> 0x827
2088 <=> 0x828
2089 <=> 0x829
4100 <=> 0x1004
5141 <=> 0x1415
5412 <=> 0x1524
6182 <=> 0x1826
8200 <=> 0x2008
9241 <=> 0x2419
20530 <=> 0x5032
21025 <=> 0x5221
26930 <=> 0x6932

I guess that works against me, but it was really luck.
