NDS Numeral Converter

About This Tool

This tool performs numeral base conversions for the NDS domain. It accepts a string representing a number in a source base (2–36) and returns an equivalent string in a target base (2–36). It validates digits against the source base, accepts optional signs, and rejects invalid characters with precise error data. The conversion uses base-agnostic arithmetic and relies on BigInt for exact integer results, avoiding overflow on very large inputs. Fractional support is available when precision is requested, enabling controlled approximation while preserving defined behavior. The design emphasizes deterministic outputs, reproducibility, and ease of automation for scripting and testing.
Core workflow involves parsing and normalizing the input, computing a decimal equivalent, and re-encoding that value in the target base. For integers, digits are produced by repeated division, while the remainder sequence forms the digits in the target base. For fractional parts, the algorithm repeatedly multiplies the fractional portion by the target base and extracts integer digits up to the requested precision. Optional options include case-insensitive input, optional uppercase output, and alignment controls. The tool returns a structured result, including the final string and a validation flag, suitable for integration into pipelines without UI dependencies.
Use cases span classroom demonstrations of base arithmetic, debugging software that manipulates encoded data, and engineers validating bit patterns, network identifiers, or encoding schemes. Distinctive value includes full 2–36 base support, strict digit validation, and deterministic, BigInt-based arithmetic that handles very large values without rounding. It is content-agnostic and API-friendly, intended to be embedded into tooling, automated tests, or CI workflows, where consistent results and explicit error reporting improve developer productivity and testing coverage.
