flawed floating-point math to be replaced by interval arithmetic

Did you know that intervals computation eliminates floting point errors? Wow!

Bill Walster:The mother of all paradigm shifts

While the inner workings of interval arithmetic are beyond the scope of this article, we can be sure of this much: Intervals work -- amazingly well. Walster uses fighter jets as a real example.
"You don't want the pilot to punch the throttle and have the engine flame out," he says, "so you have a whole set of electronics to monitor everything and not allow things to happen that will damage the engine or cause it to lose power."

In this example, more accurate equipment can mean safer planes for pilots.
"One F-16 control mechanism was altitude sensitive, so they originally had three different non-interval algorithms, derived heuristically. Trial and error. This one worked from 0 to 10,000 feet, the next one from 10,000 to 20,000 feet, and the third one from 20,000 to 30,000 feet," Walster says. "Then, in India, they developed an interval algorithm -- one algorithm for the full altitude range -- and at every altitude it was better than the other three."
Imagine the implications of this one example for product liability alone. Should a product fail and injure someone, the plaintiffs lawyer will want to know how it was designed -- using flawed floating-point arithmetic or demonstrably superior, commercially available interval analysis?
