Float (3D Analyst Tools)

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 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.
If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.

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

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.

Code sample

Float example 1 (Python window)

This example converts the input raster values to floating point.

import arcpy
arcpy.env.workspace = "C:/data"
arcpy.ddd.Float("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
env.workspace = "C:/data"

# Set local variables
inRaster = "landuse"

# Run Float
arcpy.ddd.Float(inRaster, "C:/output/outfloat")
