Interpreter with language syntax like MATLAB®/Octave
This is a scientific calculator based on MATLAB®/Octave syntax written in Javascript (Typescript). It uses the Jison parser generator to create an AST (Abstract Syntax Tree). It also uses the decimal.js API to do calculations with arbitrary precision and displays the computed math expressions in a user-friendly manner (MathML). To render MathML in browsers without support, it uses the MathJax polyfill.
The calculations can be made in a batch processing or in an interactive prompt.
