I was thinking about remakeing this mod (thinking date 07.22.25)
Lamu - Logic & Math Utilities is a mod that adds a lot of different blocks that add new ways to create logic and math systems.
Unfortunately the maximum number is (+/-1024 and 0)
Logic part of the mod is not available yet.
The mod is still in development, so it may contain bugs and therefore can only be used in creative mode.
From math blocks, mod already includes ⏬
Wires:
- digital wire
- digital up tower wire
- digital down tower wire
Operations:
- addition
- subtraction
- multiplication
- division
Inputs:
- digital number (you can set number manually)
- shift register (if powered shifts numbers)
- redstone gate (if is powered, it doesn't transmit signal)
- redstone input (converting redstone signal strength into a number)
- digital inverter
Outputs:
- digital output
- redstone output (emits signal max strenght if number is ≥ 1)
Functions.
- ReLU function (returns x if x > 0 OR 0 if x ≤ 0)
- Binary Step Function (returns 1 if x > 0 OR 0 if x ≤ 0)
- digital number round (returns 1 if x > 0 OR -1 if x ≤ 0)
Random number:
- digital random number 0 -> 10
- digital random number 0 -> 100
- digital random number -10 -> 10
