How can I do 64-bit arithmetic in Perl?

Question

I am a perl newbie,

Can I simply use 64-bit arithmetic in Perl?

For example

$operand1 = 0xFFFFFFFFFFFF;   # 48 bit value
$operand2 = 0xFFFFFFFFFFFF;   # 48 bit value

$Result = $operand1 * $operand2;

• I am basically looking for a replacement for the int64_t in perl.
• Is there any way to mention, if the variable is signed or unsigned?

Answer 1

Yes, however you need to have Perl compiled with 64-bit support.
