I have no experience with gdal_calc.pv nor do I know about its internals anything beside it being implemented with numpy. So I comment this only from a general point of view. 05.01.2016, 09:00, Avyav Kumar kirjoitti: This is a rather interesting error, which is listed here (https://trac.osgeo.

This is a rather interesting error, which is listed here ( https://trac.osgeo.org/gdal/ticket/5478). While getting the intermediate calculations of the raster band for A and B, I noticed the following - For --calc="A*20+B", the raster formed as the result of the addition of A*20 and B is not equa
