Which prompts the question, what is quad precision floating point arithmetic needed for that IBM considered it prudent to implement it in hardware of a mainframe? Who are the customers paying for such? Naively perhaps, I would expect that financial calculations (ought to) rely on fixed-point arithmetic and afaiu simulations of physical systems get away with double precision, if one is careful.

I could imagine that simulating chaotic systems needs a lot of precision. Simulation of n-body problems and others are mentioned [1].
