The property FeatValAsDouble provides access to the cell [fix,obj], given that the referenced cell is of type double. The parameter fix may assume values between 1 and NFeatures, the parameter obj may assume values between 1 and NObjects. Parameter values outside the valid range will be ignored when writing to the cell (resulting in no action at all), or a zero value will be returned when reading the FeatValAsDouble property.
Accessing cells within the valid range might generate an exception if the accessed cell is of a type other than double:
