Description
I joined a shp attribute with a csv attribute. While the two are joined in the cache the number precision in the attribute table is preserved. When I perform a save as to create a shp with the attributes joined permanently, the resulting shp converts the real numbers to integers in the attribute table.

From what I see your report is about qgis 1.8.
In QGIS master the things are a little better but still wrong, as the resulting columns have the right number of decimal places, but the values are incorrect.
Anyway it is not a regression, so is not a blocker issue.

The width values of real type fields in 2013_tissue_results.csvt are too short. With sufficient values like Real(10.3), you can see untruncated numbers in the output shapefile.

then I guess this can be closed as the original issue is fixed in master.
