It was a valid question, and to not necropost on the other, which I didn’t recall, I do support Julia explicit (about size) and I might make a type P16, because I think Posit16 might be a happy medium of sizes (see SoftPostit.jl), but not as an alias of Posit16, but with my own extension of it (base 30), stay tuned…
Some background (right now I’m focused on smaller floats for neural networks, but general purpose might needs Posit16, with or without my twist):
