Scheme numbers are tricky, see R5RS. The generic LispNumber type does not encompass all numeric types (nor does the parser), but it attempts to define interactions between floating and integer type numbers correct. It has to be redefined to adhere to the following rules:

F -> I -> F  -- implicit cast
I -> F -> F  -- implicit cast
I -> I -> I  -- no cast
F -> F -> F -- no cast
