sprintf() already returns it as a string; it's printf() that prints to the default 
filehandle. (As an aside, "%.4X" will produce the same result.)

Quite as worthy as I! But be careful with your boundary values
if they matter. I don't know what your app is, but leave it as
a sub if you can: Perl's excellent at in-line optimisation

d2h16 answers with the value, so you can

  my $answer = d2h16 31254;

It's the language that's cute: not me. Thank Larry!
