Summary

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

Illustration

OutRas = Int (InRas1)

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

LabelExplanationData 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.
