Max Hex characters set to ten?

[derrick.burns@l]

I need to track MAC address, which are hex based.
to be able to create a reliable "fill down" I created the following
formual.

=dec2hex(hex2dec(A2)+2)

Takes the hex data from the above cell (A1), converts to decimal adds 2
then converts back to hex. but only works for 10 characters.

My problem is that the MAC adress is 12 characters long.
=dec2hex(hex2dec(C6)+2, 12)
responds with the "#NUM" error.


Is there a way to adjust character limit?

Help for DEC2HEX says: If number < -549,755,813,888 or if number >
549,755,813,887, DEC2HEX returns the #NUM! error value.

If you don't actually need numbers that large but want leading zeroes to pad
out to 12 characters, you might be able to use
="00"&DEC2HEX(HEX2DEC(A2)+2,10)
but remember that the output is text, not a number.
