use either:

awk --non-decimal-data 'BEGIN { printf(int("0xff")) "\n" };'
awk 'BEGIN { printf(strtonum("0xff")) "\n" };'

And, of course, the following would work, too:

awk 'BEGIN { printf(0xff) "\n" };'

The reasons why conversion of hexadecimal numbers during runtime cannot
be enabled by default are in the manual:

   `gawk' allows the use of octal and hexadecimal constants in your
   program text.  However, such numbers in the input data are not treated
   differently; doing so by default would break old programs.

Have a nice day,
