How do I manage floating point calculations in QGIS?
I have carried out 3 consecutive calculations on landsat bands. I end up with 32 bit floating point rasters on which I can't carry out a 4th calculation. The calculation result gives a substantial file but the values of the pixels are shown as "Inf".
I am not able to find a syntax guide for the float() function although I use it successfully in 1 of the preceeding calculations. And I do not have an in-depth understanding of how to manage integer/floating point or how to convert between them in QGIS.
I found these but no big clues
