# scalar¶

scalar

Data conversion to the scalar data type

Result = scalar(expression)

expression
spatial, non spatial boolean, nominal, ordinal, directional, ldd
Result
dimension of expression scalar

## Operation¶

If expression is a PCRaster map or a calculation resulting in a PCRaster map, it is converted: the cell values of expression are assigned without change to the corresponding cells on Result. Or it generates a map of scalar data type with one constant value.

If expression has no PCRaster data type, a Result with data type scalar is generated. This is the case if expression is a number or a calculation with numbers. Result will be a map with the same location attributes as the global clone map; all cells will have the value of expression.

## Notes¶

A cell with missing value on expression is assigned a missing value on Result.

## Group¶

This operation belongs to the group of Conversion and assignment

## Examples¶

1. • pcrcalc
binding
Result = Result.map;
Expr1 = Expr1.map;
areamap
Expr1.map;
initial
report Result = scalar(1);
