Interface UserFunction

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface UserFunction
A user-defined formula function. Register with Workbook.registerFunction(name, fn); the engine calls it when a formula uses that name. Arguments are coerced to double; the result is a double.

A UDF must not call back into the same workbook while it runs.
