Welcome - HP RPN SCIENTIFIC WP 34S Owner's Manual

WELCOME!

Dear user, now you have got it: your very own WP 34S. It uses the mechanics and
hardware of an HP-20b Business Consultant or an HP-30b Business Professional, re-
spectively, so you benefit from the excellent processor speed of these pocket calculators.
And with an HP-30b you also get the famous rotate-and-click keys, giving you the tactile
feedback that has been appreciated in vintage Hewlett-Packard calculators for decades.
On the other hand, the firmware and user interface of your WP 34S were thoroughly
thought through and discussed by us, newly designed and written from scratch, loaded
with functions, pressed into the little memory available, and tested over and over again to
give you a fast and compact scientific calculator like you have never had before –
fully keystroke programmable, comfortably fitting into your shirt pocket, and RPN
The function set of your WP 34S is based on the famous HP-42S RPN Scientific of 1988,
the most powerful programmable RPN calculator industrially built so far.
the set, incorporating the functions of the renowned computer scientist's HP-16C, the
fraction mode of the HP-32SII, and probability distributions similar to those of the HP-21S.
We also included numerous additional useful functions for mathematics, statistics,
physics, engineering, programming, I/O, etc., such as
+ Euler's Beta and Riemann's Zeta functions, Bernoulli and Fibonacci numbers,
Lambert's W, the error function, and the Chebyshev, Hermite, Laguerre, and
Legendre orthogonal polynomials (no more need to carry heavy printed tables),
+ many statistical distributions and their inverses: Poisson, Binomial, Geometric,
Cauchy-Lorentz, Exponential, Logistic, Weibull, Lognormal, and Gaussian,
+ programmable sums and products, first and second derivatives, solving quadratic
equations for real and complex roots,
+ testing for primality,
+ integer computing in fifteen bases from binary to hexadecimal,
+ extended date and time operations and a stopwatch
+ financial operations such as mean rate of return and margin calculations,
+ 88 conversions, mainly from old Imperial to universal SI units and vice versa,
+ 50 fundamental physical constants as accurate as used today by national standards
institutes such as NIST or PTB, plus a selection of important constants from
mathematics, astronomy, and surveying,
+ bidirectional serial communication with your computer, as well as printing on an HP

82240A/B ,
+ battery-fail-safe on-board backup memory,
+ Greek and extended Latin letters covering the languages of almost half of the world's
population (upper and lower case in two font sizes), plus mathematical symbols.

RPN stands for reverse Polish notation, a very effective and coherent method of calculating (see p. 15).
2
The matrix menu of the HP-42S cannot be supported by WP 34S for hardware reasons. Your WP 34S
features a set of basic matrix commands and several library routines dealing with matrices instead.

The stopwatch requires adding a quartz crystal and two tiny capacitors.
4
Printing requires adding an IR diode and a resistor. Even a USB board is available for your WP 34S.
