RPN-25 CE Program Examples


Many of the pre-installed programs of RPN-25 were taken from the book HP-25 Applications Programs. Their names begin with AP, followed by the page number of the program.

You can restore or update them anytime by tapping Reload or Add Sample Programs on the program list screen.
Note that programs already listed are not restored, so any changes you may have applied to them are preserved.

Details about these programs may be found in the aforementioned book, available here (section Calculator Software Manuals).


A number of examples – all prefixed by "HC-" – are based on the wonderful book "Computational Analysis with the HP-25 Pocket Calculator" by Peter Henrici (one of the math professors of the author of RPN-25 CE.)
Prof. Henrici died 10 years after he published the book, but it's still available on Amazon (ISBN-13: 978-0471029380).
