+ *       This is due to the rounding that C compiler applies when converting a (long double) to a (long int).

+ *  In section 2.5.1.4 (Typing, overloading, and type conversion) of the IEC 61131-3 (version 2)
+ *  of the standard, it is stated:
+ * "A standard function, [...] is said to be overloaded when it
+ * can operate on input data elements of various types within a generic type designator as defined in
+ * 2.3.2. For instance, an overloaded addition function on generic type ANY_NUM can operate on data
+ * of types LREAL, REAL, DINT, INT, and SINT."
+ * [...]
+ * "When a function which normally represents an overloaded operator is to be typed, i.e., the types
+ * of its inputs and outputs restricted to a particular elementary or derived data type as defined in
+ * 2.3, this shall be done by appending an "underline" character followed by the required type, as
+ * shown in table 21."
+ *
+ * However, this explanation (as well as the example in table 21) only refers to functions where the same
+ * generic data type is used for the single input and the output parameter.
+ * How can we create explicitly types functions when this is not the case?
+ * It does not seem to be covered by the standard.
+ *
+ * For this reason, we do not define the LEN_SINT, LEN_INT, LEN_STRING, LEN_[ANY_INT], LEN_[ANY_STRING] functions...
