I'm aware I could just do 0x0 - 9223372036854775807 - 1, but is there a bit shift operation I could do instead to make this faster? Context: I'm fed a uint64 number in hex string form but I want to store this number inside an 8 byte signed integer attr in PostgreSQL. Also, I would need a way to convert it back from signed integer to unsigned hex

  • No, that performs a two's complement. This question is asking how to interpret an unsigned integer as a signed integer via the difference (i.e. the 9223372036854775807) Commented Feb 16, 2023 at 16:20
