xor, ^, pcrxor

xor, ^, pcrxor

Boolean-xor operation

Result = expression1 xor expression2 # pcrcalc
Result = expression1 ^ expression2 # python
Result = pcrxor(expression1, expression2) # python

expression1

spatial, non spatial boolean

expression2

spatial, non spatial boolean

Result

spatial; non spatial if expression1 and expression2 are non spatial boolean

Operation

The cell values on expression1 and expression2 are interpreted as Boolean values; where 1 is TRUE and 0 is FALSE. For each cell the Boolean xor evaluation is performed: if both expression1 and expression2 have a cell value 1 (TRUE) or both have a cell value 0 (FALSE) Result has a cell value 0 (FALSE) on the corresponding cell; if one of the expressions (expression1 or expression2) has a cell value 1 (TRUE) and the other a cell value 0 (FALSE) Result has cell value 1 (TRUE).

Cross table of the xor operator.

xor	expression1	Result
expression2 True	True	False
expression2 True	False	True
expression2 False	True	True
expression2 False	False	False

Notes

A cell with missing value on expression1 or expression2 or on both expressions results in a missing value on Result at the corresponding cell.

Group

This operation belongs to the group of Boolean operators

Examples

1. • pcrcalc

   binding

   Result = Result.map;

   Expr1 = Expr1.map;

   Expr2 = Expr2.map;

   initial

   report Result = Expr1 xor Expr2;

   
   

   • python

   Expr1 = readmap(“Expr1.map”)

   Expr2 = readmap(“Expr2.map”)

   Result = Expr1 ^ Expr2

   Result.map	Expr1.map	Expr2.map
