Calculate the Width of a Fuzzy Number
The width (Chanas, 2001) is a measure of nonspecificity of a fuzzy number.
## S4 method for signature 'FuzzyNumber' width(object, ...)
object |
a fuzzy number |

additional arguments passed to |
The width of A is defined as
width(A) := EI_U(A) - EI_L(A),
where EI is the expectedInterval.
Returns a single numeric value.
