Dear All,

I am wondering if it is possible to use, in the raster calculator, different mathematical functions in that the defined in the raster calc GUI.

By example, using my layer GDD (just positive values) I try this:

exp("GDD@1") but I obtained just NaN values in the result layer, the same with e^"GDD@1"


Also, if I try something like this:

"GDD@1"^2 , this worked perfect, but if I try:

2^"GDD@1" this produced just NaN

Any suggestions will be useful
