Summary

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

Illustration

OutRas = Exp10(InRas1)

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.

Parameters

Dialog

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

Python

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.ia import *
env.workspace = "C:/iapyexamples/data"
outExp10 = Exp10("degs")
outExp10.save("C:/iapyexamples/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 pixels in a raster
# Requirements: Image Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.ia import *

# Set environment settings
env.workspace = "C:/iapyexamples/data"

# Set local variables
inRaster = "cost"

# Check out the ArcGIS Image Analyst extension license
arcpy.CheckOutExtension("ImageAnalyst")

# Execute Exp10
outExp10 = Exp10(inRaster)

# Save the output 
outExp10.save("C:/iapyexamples/output/outexp10.img")
