Mathexp

Mathexp is a cross-platform mathematical expression engine designed to parse, evaluate, and manipulate mathematical expressions. It provides a compact domain-specific language for representing formulas and exposes an API that can be embedded in software written in several programming languages. The engine supports numeric evaluation with configurable precision, symbolic manipulation such as simplification, differentiation, and equation solving, and includes basic symbolic integration in optional configurations. It also offers features such as unit handling, dimensional analysis, and robust error reporting to aid debugging of mathematical input.

Mathexp originated as an open-source project maintained by a community of contributors. The core engine is implemented in C++ with language bindings for Python, JavaScript, and Java, enabling use in scientific applications, educational tools, and scientific calculators. The project emphasizes deterministic results, reproducible floating-point behavior, and a modular architecture that allows optional backends for advanced tasks.

The software is released under an open-source license (MIT) and is hosted on a public repository with accompanying documentation, API references, grammar specifications, and tutorials. It is designed to integrate with other software through a lightweight, dependency-free core and language bindings for rapid adoption.

Applications of Mathexp include educational platforms, notebook environments, web-based calculators, and data-analysis pipelines that require reliable parsing and manipulation of mathematical expressions. Limitations can include performance bottlenecks for very large expressions and reliance on optional backends for some advanced symbolic tasks.
