setting a variable from printf

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Is it posible to set a variable from the following printf statement?

#!/usr/bin/perl

use warnings;
use strict;


#hex -> dec: function hex

print hex ('0x10000a0f'), "\n";

#dec -> hex: s/printf with %x

my $val = printf "0x" . "%x\n", 268438031;
print "VAL: $val\n";

sprintf FORMAT, LIST Returns a string formatted by the usual printf conventions of the C library function sprintf. For example: # Format number with up to 8 leading zeroes $result = sprintf("%08d", $number); # Round number to 3 digits after decimal point $rounded = sprintf("%.3f", $number);	[reply]
