?Frequently Asked Questions

What is the maximum number size?

This tool uses standard JavaScript integers, so it can handle safe integers up to 2^53 - 1. For extremely large numbers, precision might be lost.

Why do we use Hexadecimal?

Hexadecimal is a human-friendly representation of binary code. Each hex digit represents 4 bits (a nibble), making it much more compact and easier to read than long strings of 1s and 0s.
