Addition

Result = expression1 + expression2

expression1

spatial, non spatial scalar

expression2

spatial, non spatial scalar

Result

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

Operation

For each cell, the values of expression1 and expression2 are summed. This sum is assigned to the corresponding cell on Result.

Notes

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

Result+=expression1 is an alternative notation for Result = Result + expression1

Group

This operation belongs to the group of Arithmetic operators

Examples

1. • pcrcalc

   binding

   Result = Result.map;

   Expr1 = Expr1.map;

   Expr2 = Expr2.map;

   initial

   report Result = Expr1 + Expr2;

   
   

   • python

   Expr1 = readmap(“Expr1.map”)

   Expr2 = readmap(“Expr2.map”)

   Result = Expr1 + Expr2

   Result.map	Expr1.map	Expr2.map
