What is a number base?

A number base (or radix) determines how many unique digits are used. Decimal uses 0-9 (10 digits), binary uses 0-1 (2 digits), and hexadecimal uses 0-9 and A-F (16 digits).

Can I convert large numbers?

Yes, but JavaScript integers lose precision beyond 2^53 - 1. For very large numbers, results may not be exact.

Why is hex useful for developers?

Hexadecimal is compact (one hex digit = 4 binary digits) and commonly used for memory addresses, color codes (#FF0000), and byte values.
