Yes, it is awkward. Yet possible.

;N means "convert to number using string-to-number".
(string-to-number "3,5") ;; => 3
why? read the docstring (it ignores non-recognized trailing chars ",5")
L makes no sense in calc formulas (it has no effect).
E refers to dealing with empty field and has no effect here.
