TL;DR

Add mininum and maximum functions to the arithmetic combinator.

What?

Add `min` and `max` to the existing set of operators, and implement them in the obvious way.

Why?

In lieu of the decider combinator getting a major upgrade, the arithmetic combinator is in need of some extra functionality, and this is a very minor feature that I have on multiple occasions wanted to have.

"Min and max are not arithmetic operations."

Then lets get rid of AND/OR/XOR and bit shifts too, because they aren't arithmetic either

"Can't the decider combinator do this?"

Glad you asked. Here's a challenge for you: I would like the maximum value of signal A and signal B output as signal C.

Code: Select all

C = max(A, B)

With my proposal it would be as simple as:

If you can show how the decider combinator can do this, hats off to you because the best I can do is maximum of A and a constant output as A:

This was already answered but you vandalized previous topic. I am not going to play cat and mouse.
