repeater only 4 bit CLE adder

[Magic :^)]

anyone ever made a cle that isnt binary?

If you mean in a different base (e.g. hex), then nope. The core of cle is the carry calculation, and that's really a base 2 job. That's how it's possible for Aft's 16 (hex) bit adder to use a binary cle layer for the carry calculation. (It goes without saying that a carry can only be 1 or 0 in the sum of 2 numbers)
In the case of that hex adder, there is 1 bit of cle carry stuff for every 1 hex (4 binary) bit of addition.
e.g.
0F + 0F = 1E
or
01111 + 01111 = 11110

So yea I got a little sidetracked there, but I can't imagine a non-binary cle to even be possible. If it was done, it would no longer be cle I think.
