Hi Alberto,

The NodeCount can exceed values of $$2^{32}$$. A double is the easiest standard data type that can cope with this. 64 bit integers might also work but they depend on the operating system, thus to not overcomplicate things, the NodeCount attribute is of double type.

Thank you so much for the kind replay Jaromił.

Excuse my ignorance about data types, but what would 166.5 nodes explored mean then?

There will be no 0.X nodes reported, i.e., you can safely convert the NodeCount to an integer. The double data type is only used to allow for very large numbers and not to report a partial NodeCount.
