Overview
Converts each pixel value of a raster to an integer by truncation.
Notes
The input values can be positive or negative.
If rounding is preferred to truncating, add a 0.5 input raster prior to performing the operation.
There is a difference between the Int function and the Round Down function. For example, given the following two values, Int always truncates the number:
 1.5 becomes 1
 1.5 becomes 1
 1.5 becomes 1.0
 1.5 becomes 2.0.
Another difference is that Round Down outputs floatingpoint values, while Int only outputs integer values.
Storing categorical (discrete) data as an integer raster will use significantly less disk space than the same information stored as a floatingpoint raster. Whenever possible, it is recommended to convert floatingpoint rasters to integer with this function.
Parameters
Parameter name  Description 

Raster  The input raster to be converted to integer. 
Extent Type  Choose which extent should be used in the output raster:

Cellsize Type  Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.
