Use printf() (or sprintf()), using either the %x or %X format
specifier:

$ perl -e'printf("%X\n", 30)'
1E

thanks guys,
I have one more question,
I have this code:
$address = ($address & zero_bits(3,11)) | (($col<<3) & 0xff8);
now, the function zero_bits returns a hex number, but it seems that
perl considers it as a decimal, and calculates wrongly the bitwise.
what should I do?!
thanks again

No. Perl does not return hex nor decimal. It returns numbers.
"hex" and "decimal" and "octal" are simply ways of displaying
representations of numbers.

You should do what the Posting Guidelines tell you to do - create a
short-but-complete script that demonstrates your problem, and post
that.

Then you'd better start a new thread...
