Hi Grass-dev, I ran into an unexpected issue (to me, at least) with r.mapcalc: I was multiplying and dividing by some pretty big scalars, and one of those was greater than a 32-bit signed value (so >2**31). What mapcalc did was to reduce that value to 2**31 and carry on with operations. There was no warning, and I didn't find any information about this on the r.mapcalc help page, so I just wanted to alert (or possibly remind) the list that this exists and note that (as a non-developer) it took me a while to figure out that this was a problem. If there is an easy way to throw an error instead of silently hitting a ceiling, or this would be important enough to put on the manual webpage, I think it would be helpful, and certainly would have saved me a ton of time.
Thanks, and happy Thanksgiving to those in the USA! Andy _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
