You can use the int-with-arg form for converting strings to integers
other than in base ten.

It wouldn't be hard to write a simple wrapping script that takes a
printf format string, converts it to a regular expression, does a match
against a string, then pulls out the arguments and converts them to
types as appropriate.  But one might just as well be using regular
expressions directly in the first place.
