Coba jelasin Interval arithmetic dari Interval (matematika) dalam bahasa sunda dong

Interval arithmetic,  also called interval mathematics, interval analysis, and interval computations, has been introduced in 1956 by M. Warmus. It defines a set of operations which can be applied on intervals :

T · S = { x | there is some y in T, and some z in S, such that x = y · z }

[a,b] + [c,d] = [a+c, b+d]

[a,b] - [c,d] = [a-d, b-c]

[a,b] * [c,d] = [min (ac, ad, bc, bd), max (ac, ad, bc, bd)]

[a,b] / [c,d] = [min (a/c, a/d, b/c, b/d), max (a/c, a/d, b/c, b/d)]

Division by an interval containing zero is not possible.

The addition and multiplication operations are commutative, associative and sub-distributive: the set X ( Y + Z ) is a subset of XY + XZ.
