The calculation of the so-called expected value is one of possible methods to deffuzify a fuzzy number.
# S4 method for FuzzyNumber
expectedValue(object, ...)a fuzzy number
additional arguments passed to expectedInterval
Returns a single numeric value.
The expected value of \(A\) is defined as
\(EV(A) := (EI_U(A) + EI_L(A))/2\),
where \(EI\) is the expectedInterval.
