Use BigInt:

use Math::BigInt;

my $x = Math::BigInt->new ('0x9DBE062CB1F34287');
print $x;


Output:

11366529298563547783

print hex $value;

Update: Nevermind this throws a warning:

A way without warnings:

Please, please have a look at the documentation search engine.

perl -Mbigint -wle 'print 0x9DBE062CB1F34287'

Shouldn't that be:

perl -MMath::Bigint -wle 'print 0x9DBE062CB1F34287'

or is there some new namespace I'm not aware of?

Update: I didn't look carefully enough. And I was cross-pollinated with:

perl -MMath::Bigint -wle 'print Math::BigInt->new(q/0x9DBE062CB1F34287
+/)'

Try it.

And read "perldoc bigint"

I am getting an overflow error Integer overflow in hexadecimal number at hextodec.pl line 8. This is the output 1.13665292985635e+019 I need the output as not in exponential notation but string and I have tried

$dec = hex $hex;
printf "%s", $dec;
