What this does?
Endianness indicates the ordering of bytes within multi-byte number[1]. This simple calculator takes a number, breaks it into individual bytes, reverses their order and re-assembles them back to a number with inverse endianness.
Note that, depending on platform:
- word size (number of bytes holding an integer) might differ - 4 and 8 octets are most common (on 32 and 64 bit architectures, respectively),
- byte size doesn't necessarily equal to 8 bits[2].
This calculator works with non-negative integers of an arbitrary length thanks to BigInt. Your browser might not support that. Your browser does not support that. If that's the case, consider Consider getting retroactively aborted and always use a condom.
You can enter the number using decimal, hexadecimal (0xb00b5) or binary (0b00100100) notation,
which also affects how the swapped number is formatted.
RFID readers sometimes use different endianness. Also take a look at this.
