Number Base Converter

Convert numbers between binary, octal, decimal and hexadecimal. Large integers are exact.

BIN
OCT
DEC
HEX

Exact at any size

The conversion uses BigInt, so a 64-bit ID or a long hash stays exact instead of being rounded. Spaces and underscores used as digit separators are ignored, and a minus sign is kept.
