public FunctionApplicationVisitor(NumericFunction function,
                                  java.lang.Number expected)
```
    Takes a function and an optionally null _expected value to compare against the function result. If the _expected value is not null, the result and value will be promoted to the same type and checked for equality.
    
    Parameters:
    
    function -
    
    expected -

```
public java.lang.Number getResult()
```
    Returns:
    
    the result of the function application. If the application was a failure, the result will be null. If the _expected value was non-null and matched the result once both were promoted, the result will be the _expected value (unpromoted).
