A partial update:
=========================================================
final Function idFunction = new IDFunction();
final Function id2Double = ff2.function("parseDouble", idFunction);
final Function modulo2Function = ff2.function("IEEERemainder", id2Double,
ff2.literal(2));
=========================================================
But the evaluation of the "parseDouble" function cannot be converted to
Number.
(I hope I am on the right way anyway :))
