| May 8, 2023 at 20:13 | comment | added | tukanium | It is the same in the QGIS 3.30.2 and to me it is a bug. The raster menu's calculator uses Foat64 and doesn't recognise -3.40282e+38 as no-data value. See github.com/qgis/QGIS/issues/47812. | |

| May 8, 2023 at 19:33 | comment | added | tukanium | Thank you for these comments. Indeed it looks like two different versions. The one that can be found in the menu seems to be the latest one (with the IF statement) but also the one that messes up no-data cells and change the original format. I will get the latest QGIS version and check again. | |
| May 8, 2023 at 18:56 | comment | added | Babel | With a look at your screenshots: both show the QGIS native Raster calculator, seem just to be different versions. The Toolbox is just the place where you find all algorithms and tools you can access on QGIS in the same place. Some also appear in the menus, others not | |

| May 8, 2023 at 18:41 | comment | added | Babel | So only no data cells are affected? The cells containing data result in the same output? In fact, there must also be a 3rd Raster calculator: QGIS native, GDAL and SAGA: gis.stackexchange.com/a/414826/88814 | |
