I am trying to convert Luojia's DN values to radiance following the equation in the attached image. equation to convert DN to radiance

I am using the Raster Calculator in ArcMap for this conversion and the command I am typing is image^(3/2)*10^(-10) but the resulting image is a binary raster with 0 and 1 values. dn_to_rad_result I tried other things as well, like inserting brackets in the equation etc but the result is the same. Why that output? From here you can download the image.

After applying the same formula using QGIS the resulting raster is a continuous raster which has a range of pixel values 0-0.08. I'm not sure if ArcMap creates a binary raster because it can't capture this small difference.
