contain zero as an interior point, a second multiplication is necessary. The result of
both multiplications is forwarded to a comparison unit. Here, for the lower bound of
the result the lower and for the upper bound the higher of the two products is selected.
This lower part of the circuitry could also be used to perform comparison relations.
In Figure 7.1 it is assumed that the second product is computed with the same cir-
cuitry sequentially. This slows down interval multiplication in comparison with the
other interval operations. This can be avoided by doubling the unit for multiplication
