Returns the next lower integer value, just represented as a floating point, for each pixel in a raster.
Input values can be positive or negative.
The output raster is always a 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. The following are examples:
Input Output 5.3 5.0 4.9 4.0 3.0 3.0 6.5 6.0 -0.2 -1.0 -2.8 -3.0
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 floating-point values, while Int only outputs integer values.
The input values to be rounded down.
Choose which extent should be used in the output raster:
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.
