Summary
Calculates the base 10 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.
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.
Syntax
Exp10(in_raster_or_constant)
Parameter | 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
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")
This example calculates the base 10 exponential of the input raster values, and returns the result as an IMG raster.
