Summary

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

Illustration

OutRas = Exp10(InRas1)

Usage

  • Input values can be integer or float, and can be negative as well as 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.

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

Syntax

Exp10 (in_raster_or_constant)
ParameterExplanationData Type
in_raster_or_constant

The input values for which to find the base 10 exponential.

In order 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

NameExplanationData 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
from arcpy.sa import *

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

# Set local variables
inRaster = "cost"

# Execute Exp10
outExp10 = Exp10(inRaster)

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