Float (3D Analyst)

Summary

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

Illustration

Float_3d (InRas1, OutRas)

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.

• 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 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
Output raster	The output raster. The cell values are the floating-point representation of the input values.	Raster Dataset

Python

arcpy.ddd.Float(in_raster_or_constant, out_raster)

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

Code sample

Float example 1 (Python window)

This example converts the input raster values to floating point.

import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.Float_3d("elevation", "C:/output/outfloat2")

Float example 2 (stand-alone script)

This example converts the input raster values to floating point.

# Name: Float_3d_Ex_02.py
# Description: Converts each cell value of a raster into a floating-point 
#    representation
# Requirements: 3D Analyst Extension

# Import system modules
import arcpy
from arcpy import env

# Set environment settings
