Calculates the base 2 logarithm of each pixel in a raster.
The input Raster can be an integer or floating point. The output of this tool is always floating point, regardless of the input type.
Input values that are 0 or negative will be NoData in the output raster.
Input values for which to find the base 2 logarithm.
Choose which extent should be used in the output raster:
Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.
