Supports arbitrary-precision integers via BigInt. Underscores are stripped: 1_000_000 works.

  1. 1
    Type into any base

    Enter a value in binary, octal, decimal, or hex - the others update instantly.

  2. 2
    Use underscores freely

    1_000_000 or ff_ee_dd are stripped to the raw digits, matching Rust and modern JS syntax.

  3. 3
    Prefixes are optional

    0b, 0o, and 0x prefixes are recognized but not required.

Is there a size limit?

No - BigInt supports arbitrary-precision integers. You can convert a 200-digit hex number just fine.

Does it support negative numbers?

Yes, in decimal. For negative hex/binary, encode with two's complement first - that's a different operation.

What about fractional numbers?

Not yet. This tool is for integers. Floats in binary/hex are a separate topic (IEEE 754).
