[netcdf-java] Question on GRIB GDS values precision (float) on computations

Hi List,
I'm using NetCDF Java 4.5.5.
I have noticed that when computing the LambertConformal projection
components (such as latin1, latin2...) in Grib1Gds I'm getting:

latin1 = 25.00001
latin2 = 25.05002
dx1 = 13.545001
dy1 = 13.545001

Instead of:
latin1 = 25
latin2 = 25.05
dx1 = 13.545
dy1 = 13.545

Plus, I'm getting some additional precision loss when extracting these
attributes
from the associated grid_mapping variable, as numbers (double values).
I will surely investigate more on the topic to become more confident with
that code and I will read again about representation errors on floating
point arithmetics so my question could sounds trivial: Why these variables
and scale constants are floats instead of doubles? (is it for size and
performance issues?)

Regards,
Daniele
