Álvaro González a6a8fafab5 feat: implement formula evaluation using d4rt interpreter - Add FormulaEvaluator class with d4rt integration - Support single output variable formulas with variable injection - Include comprehensive error handling and validation - Add 15 test cases covering evaluation scenarios - Create working example with Newton's law, quadratic discriminant, etc. - Export evaluator in main library file Implements formula evaluation by injecting variable declarations into d4rt source code, enabling execution of mathematical formulas with input parameters.		2025-08-21 18:35:50 +02:00

Math Formulae Manager

A comprehensive command-line application for managing and computing mathematical formulas across various disciplines including mathematics, physics, medicine, and engineering.

This project uses dart language, and flutter framework. It leverages d4rt library to execute formulas.
