Frequently Asked Questions

What number bases are supported?
The tool supports all bases from 2 (binary) to 36 (using digits 0-9 and letters A-Z). Common bases include binary (2), octal (8), decimal (10), and hexadecimal (16).
How do I specify the input base?
Use standard prefixes like 0b for binary, 0x for hex, 0o for octal, or the format "base r value" (e.g., "2r1010"). You can also set the input base in options.
What is digit grouping?
Digit grouping adds spaces to make long numbers more readable, like "1010 1010" for binary or "FF FF" for hex. This is especially useful for large numbers.
Can I convert negative numbers?
Yes, the tool handles negative numbers by converting the absolute value and preserving the negative sign in all output bases.
What's the maximum number size?
The tool can handle numbers up to JavaScript's MAX_SAFE_INTEGER (2^53 - 1) for accurate conversion. Larger numbers may lose precision.
