John Cominio RPN Calculator

Scientific Reverse Polish Notation Calculator. Supported functions include square root, reciprocal, change sign, sine, cosine, tangent, arc sine, cosine, tangent, hyperbolic sine, cosine, tangent, and arc hyperbolic sine, cosine, and tangent. Trigonometric functions also computed in Degrees, Radians, or Gradians.

WP 34s

WP 34s is the most powerful and complete implementation of a classic RPN scientific calculator. Now available on iOS too (see the support site for other emulators and for the real stuff).The function set of the WP 34S is based on the most powerful programmable RPN calculators built so far and we expanded the set, incorporating programmer functions (base 2, 8 & 16), a fraction mode, probability distributions, a stopwatchWe also included numerous additional useful functions for mathematics, statistics, physics, engineering, programming, I/O, etc., such as:+ Eulers Beta and Riemanns Zeta functions, Bernoulli and Fibonacci numbers, Lamberts 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 stopwatch3 based on a real-time clock,+ 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,+ Greek and extended Latin letters covering the languages of almost half of the worlds population (upper and lower case in two font sizes), plus mathematical symbols. A beginner manual can be downloaded at http://sourceforge.net/projects/wp34s/files/doc/WP_34S_Beg_Guide.pdf and a full, very complete version at http://sourceforge.net/projects/wp34s/files/doc/Manual_wp_34s_3_1.pdf

WP 31s

WP 31s is a classic RPN scientific calculator based on the powerful but more complex WP 34s. Now available on iOS too (see the support site for other emulators and for the real stuff).It is not programmable but has a rich function set for daily use and is easier to use, thanks to a less cluttered keyboard.
