Returns the next lower integer value, just represented as a floating point, for each cell in a raster.
Input values can be positive or negative.
The output raster from this tool is always floating-point type, regardless of the input value type.
If the input number has any values to the right of the decimal point, the output will be assigned the next lower integer value, but will be represented as a floating point number with no decimal portion. For example:
Input Output
5.3 5.0
4.9 4.0
3.0 3.0
6.5 6.0
-0.2 -1.0
-2.8 -3.0If 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.
If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.

Input raster or constant value | The input values to be rounded down. To use a number as an input for this parameter, the cell size and extent must first be set in the environment. | Raster Layer; Constant |
