That only works for unsigned types.
it does work for bounded signed and unsigned integers, unbounded
unsigned integers and also for floating point values (with
denormalization)
...
Signed integer types use two's complement, so the absolute value of
the largest positive and largest negative value differs.
so what?
honestly i don't catch your point
