Round Up function

Available with Image Analyst license.

Available with Spatial Analyst license.

Overview

Returns the next higher integer, as a floating-point value, for each pixel in a raster.

Notes

The input values can be positive or negative.

The input Raster can be an integer or a floating point. The output of this tool is always a floating point, regardless of the input type.

If the input number has any values to the right of the decimal point, the output will be assigned the next higher integer value but will be represented as a floating-point number with no decimal portion. The following are examples:

   Input   Output
    5.3     6.0
    4.9     5.0
    3.0     3.0
    6.5     7.0
   -0.2     0.0
   -2.8    -2.0

If the input is a multiband raster, the output will be a multiband raster. The function will perform the operation on each band in the input.

If the input is a multidimensional raster, all slices from all variables will be processed, and the output will be a multidimensional raster.

Parameters

Parameter name	Description
Raster	The input values to be rounded up.
Extent Type	Choose which extent should be used in the output raster: First Of—Use the extent of the first input raster to determine the processing extent. Intersection Of—Use the extent of the overlapping pixels to determine the processing extent. This is the default. Union Of—Use the extent of all the rasters to determine the processing extent. Last Of—Use the extent of the last input raster to determine the processing extent.
Cellsize Type	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. First Of—Use the first cell size of the input rasters. Min Of—Use the smallest cell size of all the input rasters. Max Of—Use the largest cell size of all the input rasters. This is the default. Mean Of—Use the mean cell size of all the input rasters. Last Of—Use the last cell size of the input rasters.
