Fix voice announcement rounding problem

Browse Source 
We extracted integral parts before rounding, but String.format does
rounding which caused occasional issues. To alleviate, we need to round
before passing to String.format. All this rounding logic has now been
moved into appendDecimalUnit, and tests have been added to check that
rounding works correctly.

Fixes: #1285
