There are real time environments (telecommunications, for example)
where it is better to get wrong answers (silence or noise) than late
answers.


Given such requirements, one might reasonably decide to use an
algorithm which fails occasionally because of excess floating point
precision in extended registers, if it fails quickly.


Some SCSI disk drives have a mode switch to guarantee a fast response
even if it means returning the wrong data.
