That's the same as nawk's too....

	$ nawk 'END {print OFMT}' < /dev/null
	%.6g

Oddly nothing I can find in gawk's manual talks about this weird
side-effect on "print" of changing OFMT....

Internally nawk appears to stores all numbers in C 'double' storage, but
cursory scanning of the source suggests that integer values are printed
as C 'long' integer values, while '%x', '%o', and '%u' are printed as C
'int' integer values (and '%lx' etc. are printed as C 'long' integers).
