eq or ==¶

eq or ==

Relational-equal-to operation on two expressions

Result = eq(expression1, expression2)

Result = expression1 == expression2

expression1
spatial, non spatial boolean, nominal, ordinal, scalar, directional, ldd
expression2
spatial, non spatial type of expression1
Result
spatial; non spatial if expression1 and expression2 are non spatial boolean

Operation¶

For each cell evaluates expression1 in relation to expression2. If the cell value on expression1 equals the value on expression2 Result has a cell value 1 (condition is TRUE) on the corresponding cell; if the cell value on expression1 does not equal the value on expression2 Result has a cell value 0 (condition is FALSE).

Notes¶

A cell with a missing value on expression1 and/or expression2 or is assigned a missing value on Result.

The == sign is an alternative notation for eq.

Group¶

This operation belongs to the group of Comparison operators

Examples¶

1. • pcrcalc
binding
Result = Result.map;
Expr1 = Expr1.map;
Expr2 = Expr2.map;
