Number Base Conversion is essential for translating hex values, binary flags, and decimal numbers during debugging.

Conversions:

• Hexadecimal: Base 16 (0-9, A-F)
• Decimal: Base 10 (0-9)
• Binary: Base 2 (0-1)
• Octal: Base 8 (0-7)

Usage: Type in any field, and the other fields will instantly convert the value. It also counts the active (set) bits (Hamming weight).

When you need it: Reading hex register dumps, decoding binary flag fields, or converting between decimal, hex, binary and octal while cross-referencing a datasheet and a debugger.

Worked example: 0xB4 = 1011 0100b = 180 dec = 0264 oct. Each hex digit maps to exactly 4 bits (one nibble), so a byte is always two hex digits — handy for reading memory dumps at a glance.

Tips & gotchas:

• Group binary digits in nibbles (1011 0100) to read them against hex without counting.
• Whether a value is "negative" depends on the word width you assume — 0xFF is 255 as unsigned 8-bit but −1 as signed 8-bit (two's complement).
• Mind prefixes: 0x = hex, 0b = binary, a leading 0 = octal in C.
• Widening a signed value sign-extends (copies the top bit); widening unsigned zero-extends.
