Couldn't see any way to change the precision either in the Print
composer or the main canvas window. Also, the fact that the order of
the raster legend is always negative at the top and positive bottom
(composer and canvas) is a continuing issue with rasters.

I think the precision issue creeps in when you change from the default
single band grey to singleband pseudocolor, the former has two decimal
places and the latter five. However, there should be a way, to alter
this without having to resort to building a separate qml style file to
use.

The only workaround I can find is the manually edit the legend values
and reversing the sequence.

This can be done with vectors (eg point data) but not rasters.
