PCalc Lite

This is an absolutely fabulous calculator app. I use it in RPN mode and I love it. My calculator used to be an HP 48G, but I switched to this for the quick stuff, as I was using my pc for the complexer things anyway.
There is one gripe I have, and that is the slow startup since some months now (don't know which version it started). I mean, I have this app for the quick stuff, but when it takes 20 seconds to start up, it's not quick anymore, is it?
Opening the app when it was recently used is quick though, but it's still annoying.

Mexxter: press the info/help button, then in app store, then look for lost purchases.Restored at no cost. It's really all there.
PCalc Lite is a calculator that makes me wish it had been available back when I needed the use of calculators all the time. It makes me wish that I had more calculations to work on nowadays.
Especially after adding all the optional expansion packs (don't know if that makes it equal to PCalc, the descriptions don't say), PCalc Lite has become the only calculator app for me on my iPad.
My last wish would be for a programmable pack, which adds a mode where one could enter long sequences of operations (and even save them somewhere, to reload and reuse later), and have them repeatedly be performed automatically with changing input values... Oh... Please, forgive this dreamer; sometimes he's not realistic. PCalc Lite is the best!

Ver nice calc, it can be matched with a non free calc. But there is one thing to improve. There should be one extra row to see what is bin typed. This can actually also be done in the same. Hope to see this improvent soon.

but I would love to use a [space] as a thousands seperator, and to dim the decimal positions...

PCalc Lite biedt alle standaard functionaliteit van een wetenschappelijke rekenmachine gratis en voor niets: floating point berekeningen, exponentiële, logaritmische en goniometrische functies (geen hyperbolische) en een RPN mode. De interface is aangenaam, cut, copy, paste, undo en redo worden ondersteund.
Je kunt de functionaliteit uitbreiden door vanuit de applicatie aanvullende modules te kopen. Een geniale vondst, want vrijwel niemand heeft behoefte aan de complete functionaliteit van PCalc. Voor 80 cent koop je een pakket met conversies (waaronder automatisch geupdate valutawaarden en kookboekmaten) en een verzameling fysische constanten. Pakketten voor technische berekeningen en programmeurs-functies kosten elk 2.40. Verder zijn er pakketten die thema's toevoegen, meer registers opleveren en nog zo wat.
Chique!
Het enige wat ontbreekt is een module voor statistische betekeningen ........

Finally, my best rpn calculator ever. I hope it develops even more. This app makes the iPad a precious device on it's own.
