Numbers are formatted as floating point numbers, which looks a bit crap for things like e.g. serial numbers (we don't need mantissa and exponent). This change checks the scaling factor, and if it is integer representable, the resulting number is formatted as an integer number as that's most likely what's intended, particularly if the factor is 1.

/*classes to encapsulate data from a DBC file. Really, the stuff of interest

are the nodes, messages, signals, attributes, and comments.
|
|
|
|
These things sort of form a hierarchy. Nodes send and receive messages.
|
|
Messages are comprised of signals. Nodes, signals, and messages potentially have attribute values.
|
|
All of them can have comments.
