Overview
Performs a Bitwise eXclusive Or operation on the binary values of two input rasters.
Notes
Two inputs are necessary for this function to execute.
The order of the inputs is irrelevant for this function.
If an input is floatingpoint data type, the values are converted to integer values through truncation before the bitwise operation is performed.
All bitwise operations have the following in common:
 Binary values are stored in two's complement.
 The tools work on 32bit integers.
 The leftmost bit position is reversed for the sign (positive or negative) of the value. If the integer is positive, the bit position is 0; if it's negative, the bit position is 1.
The Bitwise Xor operation treats the sign bit as it would any other bit. If one or both inputs for a pixel location are negative, the output is negative; if both inputs are positive, the output is positive.
Parameters
Parameter name  Description 

Raster  The first input to use in this bitwise operation. A constant value can be used as an input for this parameter, provided a raster is specified for the other parameter. 
Raster2  The second input to use in this bitwise operation. A constant value can be used as an input for this parameter, provided a raster is specified for the other parameter. 
Extent Type  Choose which extent should be used in the output raster:

Cellsize Type  Choose which cell size to use in the output raster. If all the input cell sizes are the same, all the options will yield the same results.

Learn more about bitwise
The bitwise tools evaluate the binary representation of the input values on a pixelbypixel basis. For each bit in the binary representation, a Boolean operation is performed.
The logic of how the various bitwise tools operate is illustrated in the following sections. The arrows are used to indicate the flow of operation of how input values are converted to a base_{2} binary representation, analyzed, and returned as a decimal (base_{10}) value.
Learn more about how Bitwise Xor works
For Bitwise Xor, for each bit where one input is 1 and the other 0, the output is 1. If both bits are 1 or both are 0, the output is 0 for the bit.
