Consider the binary value 1011 0100. Its decimal conversion would be:

  • 180 if it is an unsigned binary number
  • -76 if this is a signed binary number using standard two’s complement arithmetic.

Is there a way to instruct fend about this?

This is not currently supported, mostly because fend does not have a notion of fixed-width binary numbers. This is also why bitwise negation is not implemented. It’d definitely be nice for this to eventually be supported though.

No problems. If this is on your backlog and you might get to it some day in the future, I am happy to leave this issue open.
