## What is RPN?

RPN-32 CE is the first photo-realistic simulation of Hewlett-Packard's popular mid-range scientific calculator HP-32E for the iPhone. Produced from 1978 through 1983, it was the "Thyme" member of the third-generation HP calculators known as the "Spice" series.

While the simulator works like the original calculator, a number of carefully designed extensions make it a lot easier to use.

Unlike the HP-32E, this version is fully programmable, running virtually all programs written for the HP-25!


Features:

• Photo-realistic look-and-feel
• Programmable (99 steps), subroutines, flags, loop control, branching
• Insert and delete steps with automatic address correction
• 20 registers, "continuous", with unrestricted store/recall arithmetic
• Indirect register addressing
• "Live" register view
• Program listing view
• Program library view
• Store and retrieve any number of programs
• Sharing: e-mail, AirDrop, Dropbox, copy, paste, print
• 44 programs pre-installed
• Import GO-25 programs
• Export programs to RPN-25 CE

Calculator functions:

• Statistics (mean, standard deviation, linear regression, normal distribution)
• Factorial
• Trigonometric functions (degrees, radians, grads)
• Polar/rectangular conversions
• Hyperbolics
• Inverse, square root, logarithm, exponential, pi
• Storage arithmetic (store and recall)
• Percent change
• Percentage of Total
• Unit and hours conversions
• Many additional functions not found on the HP-32

Absolutely fantastic apps, and great customer service.

Thank you.

### 5/5 — Fantastic !

*2019-01-26*

A really realistic simulation of the HP-32E and it comes with lots of extra functions & features, especially programming. You can save programs, as many as you like. 

This is the greatest !

### 5/5 — Super HP Emulator / Best package for HP RPN Calc

*2017-01-23*

Habe selber einen HP31E und HP41C und war froh als ich dieses Paket mit den beiden HP32/38 Rechnern fand. Wäre schon super wenn es allein die Funktionen anbietet, aber so ist es noch besser, da man Programme aus dem Rechner verwalten, speichern und laden kann. Der HP32 ist erweitert, so dass man ihn auch programmieren kann und auch der HP38 kann sogar Funktionen des HP12C emulieren.
Der Entwickler antwortet schnell - alles eine runde Sache.

I own a HP31E and HP41C and was happy when I found this package with the two HP32/38 calcs. Even for having just the functions of the original would be superb, but these do organize your programs out of the calculator, save and load them. The HP32 is extended, so you can program it, and the HP38 does emulate some functionality of the HP12C. The developer answers timely - all in all a safe deal.

### 5/5 — Fabulous

*2016-06-03*

This has to be one of the most outstanding iOS applications. Realistic, well thought out enhancements. Now even supports unusual groupings which we use in India. I aim to get every application form this developer.
