D5 Converter Rhino

About This Tool

This tool converts numbers between numeral bases with a focus on the D5 (base-5) system and decimal representations. It accepts a source value and base, and outputs the equivalent in a specified target base for exact results. Conceptually, it parses the input in the source base to an internal integer and then formats that integer in the target base. This approach ensures correctness across large values and different bases. It benefits software developers, educators, and students who need quick verification of base-specific algorithms and data encodings. A unique value is robust validation, arbitrary-precision arithmetic, and consistent sign handling, enabling reliable work in algorithm testing and digital design. Core features include support for bases 2–36, signed values, and zero handling, with results suitable for further computational steps or documentation. Typical use cases include verifying base conversion routines, encoding identifiers, and teaching numeral systems in classrooms. The tool avoids any UI or front-end talk here and concentrates on the domain logic, outputs, and edge cases.
It is designed to be deterministic, with exact representations for all valid inputs and predictable behavior when digits fall outside the allowed range. The internal arithmetic path uses BigInt-like precision to prevent overflow and preserve accuracy, even for very large inputs.
By providing a simple interface for integer conversions across bases, it supports rapid experimentation and learning in fields like computer science, electronics, and numerical methods.
