The correct way to print hex number as dec number?

[Peng Yu]

Hi,

I see that --non-decimal-data must be used to print hex number as a
dec number. Is it the correct way to do so? I'd like to control this a
finer scale. Is there a way to dictate which column this option is
effective? Thanks.

$ awk --non-decimal-data '{ printf("%d\n", $1) }' <<< '0xaaaa'
43690
$ awk '{ printf("%d\n", $1) }' <<< '0xaaaa'
0
