Convert hex string from little endian to decimal

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

I am stuck trying to convert this Hex string to decimal in perl:

Hex: 5840b200

Decimal: 11681880

I am trying to do this from Hex to Dec with pack & unpack without any luck. I used unpack on an ARGV initially to get a hex string:

while(<>){
$hex_string .= unpack("H*",$_);
}

See the "Perl pack() and unpack() Tutorial" to get a basic understanding of how pack and unpack work. `$ perl -le 'my $h = "5840b200"; print unpack "I", pack "H*", $h' 11681880` [download] -- Ken	[reply] [d/l]

See hex. Update: Sorry, didn't see the bit about little-endianity. See also reverse.	[reply]
