Resumen
Finds the remainder (modulo) of the first raster when divided by the second raster on a cell-by-cell basis.

Debate
Cuando se utiliza un operador con una entrada ráster, el resultado será un ráster. Sin embargo, si todas las entradas son números, entonces el resultado es un número.
Cuando se utilizan varios operadores en una expresión, no necesariamente se ejecutan en orden de izquierda a derecha. El operador con el valor de jerarquía más alta se ejecutará primero. Para obtener más información sobre la jerarquía del operador, consulte la tabla jerarquía del operador. Puede utilizar paréntesis para controlar el orden de ejecución.
El orden de entrada es importante para este operador.
Any value modulated (divided) by zero is assigned NoData on the output; therefore, any location on the second input that is zero or NoData will return NoData for that location on the output.
The modulo operator assumes both its inputs are integers. If any inputs are not integer, those inputs will be converted to integers through truncation. Output values are always integers.
Another way to perform the modulo operator is a %= b, which is an alternative way to write a = a % b.
Sintaxis
in_raster_or_constant1 % in_raster_or_constant2
| Operando | Explicación | Tipo de datos |
in_raster_or_constant1 | The numerator input. If the first input is a raster and the second is a scalar, an output raster is created with the remainder being calculated for each input raster value after being divided by the scalar value. | Raster Layer | Constant |
in_raster_or_constant2 | The denominator input. If the first input is a scalar and the second is a raster, an output raster is created with the remainder being calculated for each input raster value after being divided into the scalar value. | Raster Layer | Constant |
Valor de retorno
| Nombre | Explicación | Tipo de datos |
| out_raster | El objeto ráster de salida. The cell values are the remainder of the division of the values in the first input by the second input. | Raster |
Ejemplo de código
% (Modulo) example 1 (Python window)
This sample returns the value of the remainder (modulus) of dividing the cells in the first raster by the second.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outMod = Raster("degs") % Raster("negs")
outMod.save("C:/sapyexamples/output/outmod.tif")
% (Modulo) example 2 (stand-alone script)
This sample returns the value of the remainder (modulus) of dividing the cells in the first raster by the second.
