## サマリー

Performs an integer divide on the values of two rasters on a cell-by-cell basis.

## 説明

ラスター入力で演算子を使用すると、結果はラスターになります。 ただし、すべての入力値が数字の場合、結果は数字になります。

この演算子では、入力の順序が結果に影響します。

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

If both inputs are integers, the output contains integer values. For example, if 5 is divided by 2, the output will be 2 (the remainder is discarded).

If either input is of floating-point type, the output quotient will be floating-point. For example, if 5.3 is divided by 2, the output is 2.0 (the remainder of 0.65 is discarded).

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

## パラメーター

 オペランド 説明 データ タイプ 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

## コードのサンプル

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

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