Exp (Spatial Analyst Tools)
Summary
Calculates the base e exponential of the cells in a raster.
Illustration
Usage
Input values can be integer or float as well as negative or positive.
You can review some results for both positive and negative floating-point input values in the examples of output values from the Exponential tools.
The base e exponential is the most commonly used exponential function.
Input values less than or equal to -745 will be set to NoData in the output, because these values cannot be accurately represented by 32-bit floating-point numbers.
The output raster from this tool is always floating-point type, regardless of the input value type.
Output values from this tool are always positive.
If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.
If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
