How about 'calculate' ? Nobody will ever exactly calculate an irrational number. At best, one can approximate the number even if one can approximate the number to any arbitrary precision. Engineers of course realize that too much precision is just a waste of time due to the limited accuracy of our measuring devices.
Joe lacks both the finesse of a mathematician and the sense of an engineer. I might suggest he is the mathematics analogue of a chainsaw carpenter except I don't think his toolbox has anything more incisive than a dull axe.
My usage might very well be nonstandard within some limited scope and that limited scope might very well contain all of c.d.t. However, I suggest the term is largely unfamiliar even within that scope, and the dictionary definition opens the doors to the nitpickers. Received on Sat Jan 20 2007 - 16:09:21 CET
