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
