# Int (Image Analyst)

## Summary

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

## 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.

• 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

 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

### Return Value

 Label Explanation Data Type Output raster The output raster.The cell values are the input values converted to integers by truncation. Raster

`Int(in_raster_or_constant)`
 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

### Return Value

 Name Explanation Data Type out_raster The output raster.The cell values are the input values converted to integers by truncation. Raster

### Code sample

Int example 1 (Python window)

This example converts the input values to integer by truncation.

``````import arcpy
from arcpy import env
from arcpy.ia import *
env.workspace = "C:/iapyexamples/data"
outInt.save("C:/iapyexamples/output/outint2")``````
Int example 2 (stand-alone script)

This example converts the input values to integer by truncation.

``````# Name: Int_Ex_02.py
