Description
Wrong handling no data value whenever I open ers files or converted to tif, which have set NULL (no data value) to -1e+32. By default QGIS 2.2 (and dev master 2.3).
Info tool and plugin value tool takes this value properly as "no data". But in properties it is handled as standard value which causes style to be adjusted to -1e+32 to -1e+29 making it blank. Also histogram is affected. Adding additional no data value -1e+32 in "Transparency" tab fix all as it should be. The problem seems to be the no data value is by default calculated by some simplified manner causing to change value -1e+32 to some close, but different (see attached image).
