A modal interval representation having improved computational utility is provided. The modal interval representation generally includes a binary quantifier, and a set theoretical interval for select permutations of marks of a pair of marks of an IEEE standard 754 digital scale. The set theoretical interval includes combinations of real numbers, infinities, signed zeros, and pseudo-numbers, with select permutations of the marks comprising bounded, unbounded, pointwise and indefinite modal intervals. |
