(for large number storage)

Default length for numeric variables is 6. This is the amount of storage space SAS allocates internally to
store the attribute values. Numeric values are stored in floating point format.
**With very large numbers, there will be some lack of precision (i.e., the numerals to the right will be ‘0’
rather than the actual number). For example, the number 18,446,744,556,876,789 might be
18,446,744,556,800,000.

NOTE
For statistical exports involving multiple landscapes, the data is sorted by
landscape, by model type, and by model. For example, data for Landscape1
occurs first by order of model type, and by order of model within each model
type (for example, ModelType1, Model1, Model2, ModelType2, Model1,
Model2, etc.). Data for Landscape2 occurs next in the same manner, and so
on for all additional landscapes.
