Summary

Converts each cell value of a raster to an integer by truncation.

Illustration

Int_3d (InRas1, OutRas)

Usage

• The input values can be either positive or negative.

• If rounding is preferred to truncating, add a 0.5 input raster prior to performing the operation.

• The maximum supported range of integer raster values is -2,147,483,648 (minimum size determined by -2³¹) to 2,147,483,647 (maximum size determined by 2³¹ – 1). If Int is used on a floating-point raster which has cells with values outside this range, those cells will be NoData in the output raster.

• Storing categorical (discrete) data as an integer raster will use significantly less disk space than the same information stored as a floating-point raster. Whenever possible, it is recommended to convert floating-point rasters to integer with this tool.

• 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.

Parameters

Dialog

Label	Explanation	Data Type
Input raster or constant value	The input raster to be converted to integer. 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 input values converted to integers by truncation.	Raster Dataset

Python

arcpy.ddd.Int(in_raster_or_constant, out_raster)

Name	Explanation	Data Type
in_raster_or_constant	The input raster to be converted to integer. 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 input values converted to integers by truncation.	Raster Dataset

Code sample

Int example 1 (Python window)

This example converts the input values to integer by truncation.
