Why do programmers use hexadecimal instead of decimal?

Hex maps cleanly onto binary (each hex digit represents exactly 4 bits), making it a compact, human-readable way to express byte values, memory addresses, and color codes without long strings of 1s and 0s.

Can it convert negative numbers?

It's built around standard unsigned positive-integer conversion across bases -- for signed/negative representations (like two's complement), you'll need to apply that convention manually to the binary output.
