Frequently Asked Questions

Trova risposte rapide

What is a hexadecimal number?

Hexadecimal is a base-16 number system that uses digits 0-9 and letters A-F (or a-f) to represent values. It's commonly used in computing and programming.

How does the conversion work?

Each hex digit is converted to its decimal equivalent (0-15), then multiplied by 16 raised to the power of its position (starting from 0 on the right). The results are summed to get the decimal value.

What characters are valid in hex input?

Valid characters are digits 0-9 and letters A-F or a-f. The input can optionally start with '0x' (e.g., 0x1A), but this is not required.

Can I convert negative hex numbers?

This calculator currently supports positive hex numbers only. For negative numbers, additional representation methods (like two's complement) would be needed.
