What would be the most "correct" way to add two `UByte`s together without overflow (e.g. 0xA3u + 0x91u becomes 0xFFu)? And the same for subtraction (e.g. 0x34u - 0x51u becomes 0x00u).

(a.toUInt() + b.toUInt()).coerceIn(0x00u, 0xFFu).toUByte()

And for subtraction would you convert to Int to handle negatives?

[diesieben07]

Ah, missed that part... yeah I guess I'd go to Int then, yeah

[Ruckus]

Cool, thanks. That's what I'm doing, I was just wondering if there's a better way I missed.

[diesieben07]

Not that I can think of anyways
