de Lugish  has defined efficient algorithms in radix 2 for certain elementary functions such as Y[X,Y/X<sup>1/2</sup>, Y + lnX, Y.exp (X), etc. His technique requires a systematic 1-bit left shift of a partially converged result, together with two 4-bit comparisons to select a ternary digit for the next iteration. This selection of digits reduces the average number of full precision additions t
