Worked on the lfortran/lfortran repository to enhance the float formatting API by introducing a FloatFormatType enum supporting 64-bit, 32-bit, and custom formats. The core dispatch logic was refactored in C to have handle_float accept the enum as its first parameter, replacing previous string-based comparisons with enum-based dispatch for improved performance and type safety. All relevant callers and function signatures were updated to align with the new API, laying the foundation for easier future extensions. This work focused on C programming, enum usage, and software refactoring, resulting in a more maintainable and extensible float formatting implementation.
