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.

Examples

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

    • python
    Expr1 = readmap(“Expr1.map”)
    setclone(“Expr1.map”);
    Result = scalar(1)
    Result.map Expr1.map
