| Wouldn't this be easier to read (and marginally faster) if written as:
| 
| if (strcmp (cname, "float"))
|   retval = any (strcmp (class (x), {"double" "single"}));
| elseif (strcmp (cname, "fnumeric"))
|   classes = {"double" "single" "uint8" "uint16" "uint32" "uint64" "int8" "int16" "int32" "int64"};
|   retval = any (strcmp (class (x), classes));
| else
|   retval = strcmp (class (x), cname);
| endif

I made this change, and used persistent variables for the cell arrays
to avoid the need for reinitializing them on each call.
