An overview of the Raster Math toolset

Available with 3D Analyst license.

Available with Spatial Analyst license.

The Raster Math tools perform mathematical operations on input rasters.

The arithmetic tools perform addition (Plus), subtraction (Minus), multiplication (Times), and division (Divide) between two inputs. The inputs can be rasters or numbers (as constant value rasters).

The remaining tools apply only to a single input raster and will either convert a floating-point raster to integer (Int) or an integer raster to floating point (Float).

License:

These Math tools are also available if you have a Spatial Analyst extension license.

ToolDescription

Divide

Divides the values of two rasters on a cell-by-cell basis.

Float

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

Int

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

Minus

Subtracts the value of the second input raster from the value of the first input raster on a cell-by-cell basis.

Plus

Adds (sums) the values of two rasters on a cell-by-cell basis.

Times

Multiplies the values of two rasters on a cell-by-cell basis.

Tools of the Raster Math toolset

A more comprehensive range of mathematical calculations (trigonometric, exponential, logical, and so forth) is available with the ArcGIS Spatial Analyst extension license.
