I'm finding this a bit extra funny having actually abused Inf, -Inf and NaN in early attempts at GPGPU stuff. Had a whole set of matrices with most being 4x4 that represented common sequences of vector ops to 2x2 ones that represented logic gates using those values. The intent of the 2x2 being to do both branches of where you needed an if-else, feed the logic result into a lerp to pick which branch's result to use further. Took while for proper hardware support for branching in shaders so everyone had weird ways to approximate it.

this strangely reminded me of little big planet. I understood little in this video but from what I could piece with the magic of nan and logic gates software can emulate hardware and hardware can be hardwired to do one task. I'm guessing this can also relate to reverse emulation?

"hello everyone today im going to weld a computer togheter and instead of using only 0 and 1 ill also add a 2 and make it a "maybe" let's see how the computer reacts to having free will !"

Firstly: brilliant video. In a strange quest to implement 3-bit floats, to familiarise myself with a new programming language, I've come to the tentative conclusion that it's impossible to follow the IEEE 754 standard with only three bits. Even using semi-IEEE-754-compliant minifloats, you need at least four bits in order to distinguish signalling NaNs from quiet ones and from infinities. I considered using the sign bit in my implementation for that job, but en.wikipedia.org/wiki/IEEE_754#Interchange_formats strongly implies that signalling NaNs need to have the most significant bit of the mantissa/significand be 0. On a three bit float, that's the whole mantissa: it's infinity, not NaN. It also says "p-1 bits...describe the significand", which is nonsensical for p=1. Is there something I'm missing? Perhaps that significand structure is optional-the standard itself isn't readily available. Perhaps minifloats don't need to distinguish NaN types-en.wikipedia.org/wiki/Minifloat doesn't mention them. Once again, a wonderful explanation, and application, of floats.
