I've never seen %0.0f and don't know what you're thinking. Just use %f or something without zeros in it. If you want integers, use %d.

I don't know how '%0.0f' could be useful, but '%.0f' can be useful to keep the length of the output correct, e.g. when it should be equal to the number of digits:
>> sprintf('%d',1e19)
ans =
1.000000e+19
>> sprintf('%.0f',1e19)
ans =
10000000000000000000
This is sometimes a more reliable way to count digits than log10 or the like.
