Description

Plus42 is an advanced scientific programmable calculator, based on Free42. Free42, in turn, is a complete re-implementation of the HP-42S scientific programmable RPN calculator, which was made from 1988 until 1995 by Hewlett-Packard. Free42 is a complete rewrite and contains no HP code whatsoever.

Plus42 builds on Free42 and adds: Algebraic expressions modeled after those used on the HP-27S and HP-17B/19B; attached units and unit conversions modeled after those used on the HP-48/49/50 series; directories for more organized storage of programs and variables; a larger display, with 8 rows and 22 columns (131x64 pixels) by default, which the user may resize at will; time value of money and amortization schedules; and two-dimensional plotting of functions, with ability to zoom and pan, and find integrals and roots from points in the plot.

A fantastic effort by Thomas Okken

Have you ever noticed that modern engineers are but a shadow of the ones that are retiring now? Well, those old people were some brutal people, not the soft squishy little engineers that graduate today.

Ask those old moldy people anything remotely technical and you will have a hard time following along. Minds sharp as razors.

Those ancient engineers used RPN calculators, and if you want to follow in their tracks you better start using one too, and this one is the best there is.
As a bonus, no one of the blue haired, nose ring adorned hippies will be able to follow along if you do a presentation.

You can use the free one, but as a developer myself I know how much work it is just to keep an app working, so do this generous man a favor and support his work by using this gem of an app, you will not be disappointed, I for sure am not.
