Rounding versus truncation estimates in difference calculations
Published online by Cambridge University Press: 06 June 2019
Extract
Two common methods of approximating difference problems are by rounding or truncating the minuend and the subtrahend before calculating the difference. Since rounding generally gives a better approximation of a number than truncation, one might expect that rounding also generally gives a better approximation in difference problems. We show that intuition to be false.
