Casio fx -5000F - Exponents

[damaltor]

That is right - but on an old calculator, on which every little firmware byte counts, why would you make two algorithms?

i rather guess that the visual style is why this was made - the calculator is heavily made for formula programming, so seeing 123²³ on the display is somewhat nicer than 123x^y23 if you try to recall what this or that formula was made for.
