Operand | Explanation | Data Type |

in_raster_or_constant1 | The input containing the values to be multiplied. If one of the inputs is a raster and the other is a scalar, an output raster is created with each cell in the input raster being multiplied by the scalar. | Raster Layer | Constant |

in_raster_or_constant2 | The input containing the values by which the first input will be multiplied. If one of the inputs is a raster and the other is a scalar, an output raster is created with each cell in the input raster being multiplied by the scalar. | Raster Layer | Constant |

## Summary

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

## Illustration

## Discussion

When using an operator with a raster input, the result will be a raster. However, if all inputs are numbers, the result is a number.

When there are multiple operators in an expression, the operators are not necessarily run in left-to-right order. The operator with the highest precedence value will be run first. For more information, see the operator precedence table in Work with operators in map algebra. Use parentheses to control the run order.

The order of the input is irrelevant for this operator.

If both input values are integers, the output values will be integers; otherwise, the output will be floating-point values.

If both inputs are single-band rasters, or one of the inputs is a constant, the output will be a single-band raster.

If both inputs are multiband rasters, the operator will perform the operation on each band from one input, and the output will be a multiband raster. The number of bands in each multiband input must be the same.

If one of the inputs is a multiband raster and the other input is a constant, the operator will perform the operation against the constant value for each band in the multiband input, and the output will be a multiband raster.

If both inputs are multidimensional rasters with the same number of variables, the operator will perform the operation for all slices with the same dimension value, and the output will be a multidimensional raster. The variables in the inputs must have the same dimensions or a common dimension but no uncommon dimensions.

If both inputs have one variable but different names, set the Match Multidimensional Variable environment to False to perform the operation.

If one of the inputs is a multidimensional raster and the other input is a constant, the operator will perform the operation for all slices for all variables against the constant value, and the output will be a multidimensional raster.

## Parameters

## Code sample

This sample multiplies the values of an input elevation raster by a constant value to convert the elevation values from meters to feet.

```
import arcpy
from arcpy import env
from arcpy.ia import *
env.workspace = "C:/iapyexamples/data"
outTimes = Raster("elevation") * 0.3048
outTimes.save("C:/iapyexamples/output/outtimes")
```
