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 stopwatch... 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 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 world’s 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

About

Pascal

This app offers a powerful 3-in-1 calculator experience, combining scientific, graphing, and programmer functionalities. The scientific calculator is free, while graphing and programmer modes require an in-app purchase, with trials available for testing.

Highlights
  • Scientific calculator (degree, radian, gradian modes)
  • RPN mode
  • Graphing calculator with smart tape and adaptive sampling
  • Programmer calculator (8, 16, 32, 64-bit bitwise)
  • Multiple numeral systems (binary, octal, decimal, hex)
  • Unicode and ASCII character encoding

Pascal (formerly Calculator³) is a professional-grade 3-in-1 scientific, graphing and programmer calculator. Scientific Calculator¹ - Supports degree, radian and gradian modes - Decimal factorials - Modulo operator - Permutations (nPr) and combinations (nCr) - Standard memory functions - RPN mode Graphing Calculator² - Includes all functions the scientific calculator offers - TI-like design - Perform calculations on a smart tape (i.e. no need to close parenthesis, multiply out brackets, real-time syntax highlighting) - Plot graphs using adaptive sampling algorithm to generate precise results - Show or hide roots/intersections and trace values Programmer Calculator³ - Supports 8, 16, 32, and 64-bit bitwise calculations - Binary (base-2), octal (base-8), decimal (base-10), and hexadecimal (base-16) numeral systems too - Unicode (UTF-16) and ASCII character encoding - A binary table that shows you in real time the binary representation of the current operand - RPN mode

Verdict

The call

The clearest difference is price: WP 34s at Free against Pascal's $2.99. WP 34s also leads on rating (4.7 vs 4.0) and in-app purchases (none vs 3). Pascal's advantage is update cadence (every 2 weeks vs every 4 months). On ratings volume, ads and device support there is nothing between them.
