Auiu (aka RPN) notation ...

[raprism]

RPN for calculators is not dead, but a niche. But not only for RPN calculator fans the reversed notation might make more sense to have fun with such a versatile language like Uiua seems to be.

I have to admit that I am quite a novice with Uiua, so my experience is very limited. But I wonder if there are serious limitations, if one would introduce an Auiu mode ;-)

If you write functions separated by ;, they will be flipped when formatted. This allows you to write things from left to right, RPN-style. For instance, if I want to push 4 and 9, then multiply them, then square root the result, I can write these instructions left to right like 4 9;mul;sqrt and it will format to √×4 9, which does the operations in the order I wanted.

Good to know. Thank you.
