Number converter
Edit any row—binary, bytes, hex, unsigned or two’s-complement signed int, or ASCII—and the rest stay in sync. Big-endian, MSB on the left.
Multi-byte value; byte columns are left to right from most significant to least.
Unsigned range:
0 … 256n - 1. Signed (two’s complement): -28n-1 … 28n-1 - 1. Copy actions use the last committed value. Very large fields may hit JavaScript’s safe integer limit (2^53 - 1).
