that's simply a function of what's present in your input data.
for floating point values it will just be the next highest

see also the output of r.univar and the display histogram tool.

it's the same thing, just that the default options have been
explicitly, instead of implicitly, listed.

output= should not be given an @mapset part, as output is
always in the current mapset.
