What bases are supported?

Any base from 2 (binary) to 36 (using digits 0-9 and letters A-Z). Common bases like 2, 8, 10, and 16 are shown by default.

Can I convert very large numbers?

Yes. The tool uses JavaScript's BigInt for arbitrary-precision integer arithmetic, handling numbers of any size without precision loss.

How does floating-point binary work?

Fractional parts are converted by repeatedly multiplying by 2 and recording the integer part. The tool shows up to 32 binary fraction digits.

What does the step-by-step view show?

For base-10 → base-2 it shows repeated division by 2. For base-2 → base-10 it shows the positional weight of each bit.

关于此工具

A comprehensive number base converter that handles bases 2 through 36. Enter a number in any base and instantly see its representation in all other common bases simultaneously. Supports arbitrary-precision integers, negative numbers, and floating-point binary fractions. Binary output is grouped into nibbles (4 bits) and bytes (8 bits) for easy reading. Step-by-step conversion working is shown for base-10 ↔ base-2 to help you learn the algorithm.

使用方法

1 Select the input base using the dropdown or type a custom base (2–36).
2 Type your number in the input field. Use A–Z for digits above 9.
3 All output bases update instantly. Toggle negative with the ± button.
4 For floating-point, include a decimal point (e.g. 3.14 in base 10).
5 Click 'Show Steps' to see the base-10 ↔ base-2 conversion working.
