Minecraft 1.16.5

Uses overloaded Signal Strength, which is achievable in vanilla survival, to convert binary in to BCD then Dec(Signal Strength Coded Decimal).

The concept is really simple, basically I'm checking if input X0 >= A0, if true, X1 = X0-A0, else, X1 = X0. Do that for An = 200, 100, 80, 40, 20.....
until you get the BCD output. This is the same method used for normal analog to binary transcoders, but I realised that if I could design one that doesn't use dust, I can use it for overloaded signals too.

I designed a pistonless version too, but would hight recommend against it as it's much more complecated.
