Important
Check the result before relying on it
Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.
Practical details
What this Lucaden tool does
BigInt parsing avoids floating-point rounding for large integers. Optional prefixes such as 0x and 0b are normalized when they match the selected input base.
The transformation happens in browser memory and produces a new result without changing the source on your device.
