But you can write your own function, for example :

Code:
function toHexa(number, len      ,str) {
   if (len == 0) len = 2;
   str = sprintf("%0" len "." len "x", number);
   return substr(str, length(str)-len+1) "";
}
{
   print $1, "=>", toHexa($1,3);
}

Input:
Code:
0
1
27
3210
-1
-30

Output:
Code:
0 => 000
1 => 001
27 => 01b
3210 => c8a
-1 => fff
-30 => fe2

NAME
gbase - small numeric base converter SYNOPSIS
gbase [options] DESCRIPTION
gbase converts numbers between bases 2 (binary), 8 (octal), 10 (decimal), 16 (hexadecimal). If you specify a number on the command line (preceded by a switch to describe the base the number is in) the program will display that num- ber in the four bases on the console and exit. You can also specify the -s switch which will allow you to enter/display signed numbers. (This allows the use of a - (minus) before a deci- mal number). Just running the program without any switches will display the main window. There are four entry boxes, corresponding to each of the four bases. You can type into any of these boxes and the others will update automagically. The program will ignore any characters that are not allowed for that particular base. It will only allow a - (minus) at the start of a decimal number, if the signed option is on. OPTIONS
--help Display a short help screen and exit --version Print version number and exit -s Treat the number as a signed value -d decimal number Print this decimal number in all bases -h hex number Print this hexadecimal number in all bases -o octal number Print this octal number in all bases -b binary number Print this binary number in all bases AUTHOR
