Hi Pedro, thank you very much to have tested the computation with my test data! You are right, I checked again the computation and actually it works.
However, I was using Saga raster calculation in a processing modeler, and one of the layer I share with you is the resulting from a previous computation. In other word the raster layer c=temp_recal.tif comes from a previous computation (raster calculator): ifelse(a>0,-(0.0065*a-16),(0.0045*a+16)) where a is the layer attached, and hence c of the previous formula is the resulting of this first computation.

Z_top_res.tif have values from 724.403 to 1423.553, and so, the first condition is never true. Then, it always make ((b-c)/a)*1000, and the result seems ok to me.

I tried also r.mapcalc, but I got a worst result.
