Using the Raster Calculator to set output parameters

The Single Value option gives you a single-number result for a single-band computation in the status bar of the calculator tool.

The Display option is the result of a computation on one or more bands that produces a band. This output field can be saved to disk and can be shown in the Focus window.

From the Tools menu, click Raster Calculator.
Click in the Expression box.
Using the calculator buttons, enter an equation in the Expression box and specify Add to existing file.
Enter an equation in the Expression box and specify Add to new file, channel description, and channel type into the output parameters.
Enter an equation in the Expression box that results in a single integer value. When no output parameters are specified, the Raster Calculator checks for errors in the equation (such as parentheses not closed), calculates the result, and displays it in a new window.

Many of the same formatting rules for EASI Modeling apply to the Raster Calculator.
