BITXOR()

Purpose

Function to perform bitwise XOR (exclusive OR) operation

Syntax

BITXOR(<expN1>,<expN2>[,...<expN26>])

See Also

BITAND(), BITCLEAR(), BITLSHIFT(), BITNOT(), BITRSHIFT(), BITSET(), BITTEST()

Description

The BITXOR() function performs a bitwise XOR (exclusive OR) operation on the specified numeric parameters. Up to 26 parameters can be specified. These parameters, if not integers, will be converted to integer values before the operation takes place.

BITXOR() compares each bit in turn of <expN1> and <expN2>. If only one of the bits is 1, the corresponding bit in the result is set to 1, otherwise the result bit is 0. If <expN3> is specified, the initial result is compared bit by bit with <expN3> and a new result evaluated. This new result is then compared with <expN4>, if specified, and so on.

<expN1> bit	<expN2> bit	Result bit
0	0	0
0	1	1
1	1	0
1	0	1

Example

x = 3			&& 0011
y = 6			&& 0110
z = 7			&& 0111
? bitxor(x,y)
         5		&& 0101
? bitxor(x,y,z)
         2		&& 0010
