Pentatronics 1000 vs SwiftRPN

Pentatronics 1000 is a faithful re-creation of the legendary gaming calculator, one of the most exciting calculators of its era. Pentatronics 1000 introduced many novelties such as the iconic "READY" message that has been adopted by virtually every calculator ever since. Today we take for granted that a calculator should have at least one game, but this was again an innovation brought by Pentatronics. Pentatronics creators believed that life shouldn't be just about math and logic. Fun, style, and humor were every bit as important. Unfortunately, today these calculators are impossible to find except in the hands of a few lucky collectors. We are honored to bring this rare calculator to your mobile device. We would like to thank all the people who helped us during the development of this app, especially Edwin J. Gallaghan from the original Pentatronics 1000 development team. Without Edwin's expertise and warm encouragement, we couldn't have completed this project. For feedback, contact us at pentatronics1000@gmail.com.

SwiftRPN is an RPN (Reverse Polish Notation) calculator that aims to be quick to open and easy to use. = RPN Stack Work quickly and efficiently using the RPN Stack by pushing and popping values. The stack will always show what series of inputs led to each output, so you won't lose context during complicated expressions. = Extended Types SwiftRPN can understand scalar types like integers and real numbers, as well as vectors and square matrices of sizes 2, 3, and 4. When operating purely in the scalar integer domain, SwiftRPN can promote up to BigInts to avoid floating point imprecision. = 80 Operators SwiftRPN has 84 built-in operators with included documentation and examples. All the expected operators (basic arithmetic, exponents, logarithms) are present, as are: - Rounding functions (floor/ceil/trunc/round) - Unit conversions - Bitwise operations (and/or/not/xor/shift left/shift right) - Statistics (avg/min/max/sum/std dev/NPV) - Trigonometry (sin/cos/tan + arc/hyperbolic variants) - Vector operations (dot/cross/normalize/length/swizzle) - Matrix operations (identity/inverse/transpose + translation/scale/rotation matrix generators) = Unit Conversions SwiftRPN has 74 built-in units, and can convert between units within families, including: - Angle - Area - Colors (3 and 4 components) - Coordinate systems (2D and 3D) - Length - Mass - Storage (Base 10 [SI, 1000 bytes in a kb] and Base 2 [1024 bytes in a kb]) - Temperature - Time - Volume = Value Representation SwiftRPN recognizes values represented in binary, octal, decimal, and hexidecimal. You can: - Enter values in one representation, and convert them to another - See the result of bitwise operations in binary automatically - View vec3 and vec4 components (truncated) in hexidecimal when working with colors.
