Developed a mathematical and symbolic constants library for the uiua-lang/uiua repository, expanding the language’s capabilities to support advanced symbolic and numerical computations. The work introduced constants such as the golden ratio, Euler-Mascheroni constant, and symbolic representations for planets, zodiac signs, and chemical elements, laying the foundation for richer analytics and simulation workflows. Leveraging Rust programming and language development expertise, the implementation focused on clear structure and extensibility, with explicit commit and issue tracking to ensure transparency and collaboration. This contribution enhanced the mathematical expressiveness of the language, supporting future growth in mathematical and symbolic computation within the project.
