Hi Martin
Thanks for looking at the patch. Your point about the search string makes
sense. I decided to use the search string because of code reusage and the idea
of introducing some comparison operators for raster algebra in the future
(e.g. ras...@1 10 would return a raster with 1 for
the same problem arises in the vector calculation dialog. I had to
rename the vector fields.

Hi
Our community prepare QGIS binaries with raster algebra patch
for OSGeo4W users who want to test this great improvement.
Here is a short installation instructions:
1. install qgis-dev with all dependencies from OSGeo4W
2. download archieve with binaries (~8.2 Mb compressed with 7-zip)

Hi Marco,
seems that this is another great addition from your side.
I'll try to build QGIS trunk (r14380) with this patch under
Windows with MSVS Express 2008 and dependencies from OSGeo4W
and get next error:
qgssearchtreenode.cpp
d:\devel\cpp\qgis\trunk\src\core\qgssearchtreenode.cpp(1304) :
And another minor issue.
I have raster 2007.tif. When I enter expression
2...@1 + 2...@2
I get Expression invalid message. Seems that raster names
only with digits and symbols minus (-) don't recognized as
valid raster names

I change line 1304 as
res[i] = pow(double(value1), double(mat[i]));
value1 is already double. So casting mat[i] should be enough.
and the I get another errors:
qgisapp.obj : error LNK2019: unresolved external
