Byte Representation:
Decimal: 170
Binary: 10101010
Hex: AA
Signed: -86 (two's complement)
Two's Complement:
Positive: 0111 (7)
Negative: 1001 (-7)
Calculation: Invert bits + 1
0111 → 1000 + 1 → 1001
Signed vs Unsigned: Our converter handles both signed (two's complement) and unsigned representations, showing both interpretations for the same binary pattern.
