Summary
Returns the next higher integer value, just represented as a floating point, for each cell in a raster.
Illustration
Usage
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 higher integer value, but will be represented as a floating point number with no decimal portion. For example:
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 tool will perform the operation on each band in the input.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
RoundUp(in_raster_or_constant)
Parameter | Explanation | Data Type |
in_raster_or_constant | The input values to be rounded up. 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 |
Return Value
Name | Explanation | Data Type |
out_raster | The output raster. The cell values are the result of rounding up the input values. | Raster |
Code sample
This example rounds the values in the input raster to the next higher integer value and outputs a floating-point raster.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outRoundUp = RoundUp("gwhead")
outRoundUp.save("C:/sapyexamples/output/outru")
This example rounds the values in the input raster to the next higher integer value and outputs a floating-point raster.
