Description
Method Abs Calculates the absolute value of cells in a raster.
Method Divide Divides the values of two inputs.
Method Exp Calculates the base e exponential of cells in a raster.
Method Exp10 Calculates the base 10 exponential of cells in a raster.
Method Exp2 Calculates the base 2 exponential of cells in a raster.
Method Float Converts a raster into floating point representation.
Method Int Converts a raster to integer by truncation.
