Summary

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

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.

Syntax

Float_3d (in_raster_or_constant, out_raster)
ParameterExplanationData 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
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
env.workspace = "C:/data"

# Set local variables
inRaster = "landuse"

# Execute Float
arcpy.Float_3d(inRaster, "C:/output/outfloat")
