# Exp10 (Spatial Analyst)

## Summary

Calculates the base 10 exponential of the cells in a raster.

## 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.

• Input values less than or equal to -324 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.

• In ArcPy, if the input is a multidimensional raster, all slices from all variables will be processed, and the output will be a multidimensional raster.

• See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.

## Parameters

 Label Explanation Data Type Input raster or constant value The input values for which to find the base 10 exponential.To use a number as an input for this parameter, the cell size and extent must first be set in the environment. Raster Layer; Constant

### Return Value

 Label Explanation Data Type Output raster The output raster.The cell values are the base 10 exponential of the input values. Raster

`Exp10(in_raster_or_constant)`
 Name Explanation Data Type in_raster_or_constant The input values for which to find the base 10 exponential.To use a number as an input for this parameter, the cell size and extent must first be set in the environment. Raster Layer; Constant

### Return Value

 Name Explanation Data Type out_raster The output raster.The cell values are the base 10 exponential of the input values. Raster

### Code sample

Exp10 example (Python window)

This example calculates the base 10 exponential of the input raster values.

``````import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outExp10 = Exp10("degs")
outExp10.save("C:/sapyexamples/output/outexp10")``````
Exp10 example 2 (stand-alone script)

This example calculates the base 10 exponential of the input raster values, and returns the result as an IMG raster.

``````# Name: Exp10_Ex_02.py
# Description: Calculates the base 10 exponential of cells in a raster
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
