reflectance value ranges from -3.40282e38 to 3.40282e38 in qgis atmoshpherically corrected image, I want my value to range between 0-1 how can i fix this?

The standard way to map into the range $$[0,1]$$ is by using the sigmoid function, however, such a large range will lead to very similar values.
