## Resumen

Divides the values of two rasters on a cell-by-cell basis.

## Debate

Cuando se utilice un operador con una entrada de 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 por orden de izquierda a derecha. El operador con el valor de jerarquía más alto será el que se ejecute primero. Para obtener más información sobre la jerarquía del operador, consulte la tabla de jerarquía del operador. Puede utilizar paréntesis para controlar el orden de ejecución.

When a number is divided by zero, the output result is NoData.

The exact division technique used by this operator depends on the application being used when performing it.

In ArcGIS Pro, the floating-point division of Python 3 is always used for this operator, and the output will always be a floating-point value. For example, if 3 is divided by 2, the output is 1.5.

In ArcMap, the divide operator employs the integer division technique of Python 2, where only the integer quotient is retained. If both inputs are integers, the operator performs an integer division, and the output will be an integer. For example, if 3 is divided by 2, the output is 1, or if -3 is divided by 2, the output is -2. If either input is of floating-point type, the divide operator performs a floating-point division, and the output will be a floating-point value. For example, if 3 is divided by 2.0, the output is 1.5.

##### Nota:

Keep this difference in mind if you are migrating from ArcGIS Desktop to ArcGIS Pro, or you will be working in a mixed environment of both. You can use the // (Integer Division) operator if it is important to maintain the integer output.

Another way to perform the divide operation is a /= b, which is an alternative way to write a = a / b.

Si ambas entradas son rásteres de una banda o una de las entradas es una constante, la salida será un ráster de una única banda.

Si ambas entradas son rásteres multibanda o una de las entradas es una constante, la salida será un ráster multibanda. El número de bandas en cada entrada multibanda debe ser el mismo.

El operador realizará la operación en cada banda de una entrada con respecto a la banda correspondiente de la otra entrada. Si una de las entradas es un ráster multibanda y la otra entrada es una constante, el operador realizará la operación con respecto al valor constante de cada banda de la entrada multibanda.

## Sintaxis

`in_raster_or_constant1 / in_raster_or_constant2`
 Operando Explicación Tipo de datos in_raster_or_constant1 The input whose values will be divided by the second input.If the first input is a raster and the second is a scalar, an output raster is created with each input raster value being divided by the scalar value. Raster Layer | Constant in_raster_or_constant2 The input whose values the first input are to be divided by.If the first input is a scalar and the second is a raster, an output raster is created, with each input raster value 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 quotient of the first input raster (dividend) divided by the second input (divisor). Raster

/ (Division) example 1 (Python window)

This sample divides the values of the first input raster by the second.

``````import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outDivide = Raster("degs") / Raster("negs")
outDivide.save("C:/sapyexamples/output/outdivide")``````
/ (Division) example 2 (stand-alone script)

This sample divides the values of the first input raster by the second.
