Using ArcMap 10.3, I am trying to perform map algebra on a raster with 2013 annual PRISM precipitation for the U.S. (http://prism.oregonstate.edu/recent/). The raster has 1 band an is floating point.
Using Spatial Analyst Tools > Map Algebra > Raster Calculator (i.e. not within model builder), I have tried to create a new raster by executing these expressions (separately):
"PRISM_ppt_stable_4kmM3_2013_asc.asc" * 0.1 and Float("PRISM_ppt_stable_4kmM3_2013_asc.asc" * 0.1)
Both expressions yield this error:
Raster(r"PRISM_ppt_stable_4kmM3_2013_asc.asc") * 0.1
ERROR 000539: Error running expression: rcexec()
Traceback (most recent call last):

["Times", in_raster_or_constant1, in_raster_or_constant2])
RuntimeError: ERROR 999998: Unexpected Error.
Failed to execute (RasterCalculator).
What am I missing here?
