Calculators for Mac Os

[pier4r]

I tried to search something but I was not that lucky.

I would like to, well, keeping the comfort zone having a calculator for mac. The point is to have a math environment without the need to open excel or other programming languages (that are surely powerful, but they do not have memory between sessions unless I click "save" or I code persistency. For example with 'bc').
There is little to do, the "continous memory" of calculators is pretty handy more often than not for some calculators.

I am not fan of emulators, but between not having a feature and having it emulated, also emulators are fine.
I tried on hpcalc.org and I found a version of emu48, but it works for the powerPC architecture.
Does someone know any nice calculator with continous memory (without me clicking save) for mac? It doesn't stricly matter if it is RPN/RPL.

Yes I thought about the prime. But I bought it for windows and android and I don't want to "abuse" the free virtual calculator.
Surprisingly (or not) there are not much calculators done for mac.

In the meanwhile I continue the search.

Ah, for those in my same situation but that search for android, check here: http://www.hpmuseum.org/forum/thread-802...l#pid70348

update1: just found the ubiquitous and great http://thomasokken.nl/free42/ . Nonetheless alternatives are welcome. I cannot really find a good search string on search engines.
