Pali vs SwiftRPN

“Madam, I'm Adam." "Able was I ere I saw Elba." A palindrome is a sentence that is the same whether it is read from the front or the back. Thinking up palindromes on your own is a fun but quite difficult mental exercise. With this application, you will be able to efficiently experiment with different types of palindromes. If you find a palindrome you like, save it as a favorite or share it with your friends. // Main functions // - When a character is entered in either the upper or lower frame, it will appear in the opposite frame in reverse order to create a palindrome. - The contents of the upper and lower frames can be swapped at the touch of a button, and whether or not the last character in the upper frame is repeated can be toggled. - You can also copy palindromes to the clipboard and save them to your favorites. - Saved palindromes are listed and can be deleted, reordered, or recalled. - You can also share your palindromes on Twitter.

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. = 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.
