Summary
Converts each cell value of a raster into a floating-point representation.
Illustration
Usage
The input values can be positive or negative.
If you execute on an input that is already floating point, the output values will remain the same as the input values.
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
Float(in_raster_or_constant)
Parameter | Explanation | Data Type |
in_raster_or_constant | The input raster to be converted to floating point. 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 floating-point representation of the input values. | Raster |
Code sample
This example converts the input raster values to floating point.
import arcpy
from arcpy import env
from arcpy.ia import *
env.workspace = "C:/iapyexamples/data"
outFloat = Float("landuse")
outFloat.save("C:/iapyexamples/output/outfloat2")
This example converts the input raster values to floating point.
# Name: Float_Ex_02.py
# Description: Converts each pixel value of a raster into a floating-point representation
# Requirements: Image Analyst Extension
# Import system modules
import arcpy
from arcpy import env
