how to convert a number from hex ==> decimal?

Hi,
Can someone please post me a way of converting a hex number to it's decimal equvalent using perl.

In a UNIX shell script, I would have a variable set. eg.

hex_nbr="A"

.....and then I would like perl to take this variable as input and output a new variable with decimal equivalent. ie. dec_nbr="10"

Regards,
Adam

you can...

$dec_nbr = hex("A");

hex() converts hex to decimal.

Thanks - works like a charm!
