ErlangBigInteger

[Source]

An integer wider than 64 bits.

It is kept the way the external format keeps it - a sign and a magnitude in base 256, least significant byte first - so nothing is lost on the way in or out, and decimal() is only computed when a person needs to read it.

The magnitude is normalised on construction: trailing zero digits are dropped and zero is stored as no digits with a positive sign. An integer that fits into 64 bits arrives as ErlangInteger instead, so a value that was built here can decode as a different class.

class val ErlangBigInteger is
  Equatable[ErlangBigInteger val] ref,
  Hashable ref,
