With Radare when I do ?, I get a list of answers in the result,

[0x00400a04]> ? -0x120 + 0x110
hex     0xfffffffffffffff0
octal   01777777777777777777760
unit    17179869184.0G
segment fffff000:0ff0
int64   -16
string  "\xf0\xff\xff\xff\xff\xff\xff\xff"
binary  0b1111111111111111111111111111111111111111111111111111111111110000
fvalue: -16.0
float:  nanf
double: nan
trits   0t11112220022122120101211020120210210211100

All of these I understand, except a trit -- the last one. What is this used for?

3

It's simply the value of the expression shown in the base of 3.

[0x100001200]> ? 3
hex     0x3
octal   03
unit    3
segment 0000:0003
int32   3
string  "\x03"
binary  0b00000011
fvalue: 3.0
float:  0.000000f
double: 0.000000
trits   0t10

The implementation of it is in the unum.c file.

Trit is just an equivalent of bit in the base of 2. Have a look at ternary numeral system on Wiki.

  • But is this used at all ever, or is it there for just novelty? – Evan Carroll Oct 6 '18 at 15:32
  • it's just for convenience. If you need the value in base 3 you have it there. Not sure if I've ever used it ;) – Paweł Łukasik Oct 6 '18 at 16:07
  • I think it's there more for amusement than functionality. Seeing it there is funny, if you're into that kind of humor :D – NirIzr Nov 20 '18 at 5:23

Apparently this is used for binary-coded ternary stuff, or would be anyway if anyone ever used it.

You can find a library which this may actually be used for here.

I think it's total novelty.
