Unless you're a computer scientist studying algorithms, probably not. But when I defended my Master's thesis in CS way back in 1983 - yes, I'm that old - my fiancee[1] gave me the three-volume set of Knuth as a graduation gift. I had used his algorithm for arbitrary precision arithmetic in my thesis project. I had figured out addition and subtraction trivially, and had gotten multiplication on my own, but division eluded me. I credit Knuth in part for my being able to graduate with my M.S. Also: my thesis advisor had found a mistake in an earlier edition and was credited in the notes in the back of one of the volumes. So: your mileage may vary. [1] Still married, 35 years at last count.
