# logxor

Type: | - | function (subr)
Source: | - | xlmath.c

## Syntax

(logxor expr1 ... )
  exprN - an integer expression
  returns - the result of the eXclusive OR operation

## Description

The 'logxor' function returns the logical bitwise 'exclusive-or' of the list of expressions. If there is only one argument, it is returned unaltered. If there are two or more arguments, the 'logxor' function performs the 'exclusive-or' successively applying the bitwise operation.

## Examples

    (logxor 0 0)                  ; returns 0
    (logxor 0 1)                  ; returns 1
    (logxor 1 0)                  ; returns 1
    (logxor 1 1)                  ; returns 0

    (logxor #b0011 #b0101)        ; returns 6
    (logxor 255 #xF0)             ; returns 15
    (logxor 255 #x0F)             ; returns 240
    (logxor 255 (logxor 255 99))  ; returns 99

Note: XLISP does not check when read-macro expansions like '#x0FF' are out of bounds. It gives no error message and will just truncate the number to the low-order bits that it can deal with [usually 32 bits or 8 hex digits].

See the logxor function in the XLISP 2.0 manual.
