here:

hex EXPR

Example:

print hex "10";

Output
16

Read this Manual:

thank you for answering me but :
in fact, what i look for is the reverse conversion.
how to get 10, by writing :
print "hexadecimal equivalent of 16";

You can use sprintf to do that trick...

$var = sprintf "%lx", 16;
print "$var\n";


HTH

thank you, your trick is exactly what i was lookin' for !

I used this two function : pack and unpack

For exemple :

$input = "string";
$var = unpack "H*", $input;
print $var;
