Is there a convention for negative hex numbers?
-0xFEEE

0x-ABCD
I would use the first one, because this would be the convention for using
in C programs. But it depends on the language. E.g. in Forth you can switch
the context and any numbers are interpreted and printed with the new radix:
Thanks; I'll use the first one.
hex ok
-babe cafe +
. 1040 ok
PS: -0xfeee is not possible, if you use 16 bit, because usually they are
saved as two's complement.
Sure it's possible. Poke 0xFEEE into a 16-bit register, then negate
it. So -0xFEEE = 0x0112.
