I have a temp raster in celsius*10 units and wanted to get down to celsius by doing this: {{{ UPDATE t SET rast = ST_Reclass(rast,1,'-9000-9000:-900-900'::text, '32BF'::text); }}} Results all come out NULL, but {{{ UPDATE t SET rast = ST_Reclass(rast,1,'0-9000:0-900'::text, '32BF'::text); }}} seems to work as expected Am I missing something. If so not clear from the docs how someone can reclassify negative numbers. There are some examples in the regress tests though none of those seem to amp a negative to a negative number and one even uses the letter a? {{{ 'a-100]:50-1,(-100-1000]:150-50,(1000-10000]:254-150' }}} what the heck does that mean? at any rate if this is not a bug, it should be documented as its not intuitively obvious.",defect,closed,medium,PostGIS 2.0.5,raster,2.0.x,fixed,history,
