Float (Spatial Analyst)

Summary

Converts each cell value of a raster into a floating-point representation.

Illustration

OutRas = Float (InRas1)

Usage

• The input values can be positive or negative.

• If you execute Float on an input that is already floating point, the output values will remain the same as the input values.

Syntax

Float (in_raster_or_constant)

Parameter	Explanation	Data Type
in_raster_or_constant	The input raster to be converted to floating point. 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

Name	Explanation	Data Type
out_raster	The output raster. The cell values are the floating-point representation of the input values.	Raster

Code Sample

Float example 1 (Python window)

This example converts the input raster values to floating point.

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outFloat = Float("landuse")
outFloat.save("C:/sapyexamples/output/outfloat2")

Float example 2 (stand-alone script)

This example converts the input raster values to floating point.

# Name: Float_Ex_02.py
# Description: Converts each cell value of a raster into a floating-point representation
# Requirements: Spatial Analyst Extension
# Author: ESRI

# 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 = "landuse"

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

# Execute Float
outFloat = Float(inRaster)

# Save the output 
outFloat.save("C:/sapyexamples/output/outfloat")
