Has combinations, permutations and graphs, not much else that isn’t standard.

What I want is normal distribution, cumulative normal, Poisson distribution, Weibull distribution and error function.

Any calculators that have that?

For doing more than basic calculations, and plotting graphs, what advantage do people see in a calculator, compared with a spreadsheet?

And what is the advantage of an on-line tool, compared with one on your hard disk, which is easily available all the time?

Nostalgia mostly, typing 58008 on a calculator and turning it upside brings back fond memories
