You’re quoting the help for %x for strings and byte slices. For integers it simply says "base 16, with lower-case letters for a-f” and thus behaves like any other number base usually does. In this case, you want “%02x”.

The documentation of %x for sprintf made me think that this would keep a left padded zero on my string for 0-9, so I merely abstracted my sprintf to check if it's lower than 10 and then pad it to make it look like a proper mac address. I would love to come up with some better verbiage for the description in the documentation for 0-9 so people arent surprised and need to left pad it like I had to for a mac address %x base 16, lower-case, two characters per byte -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
