Issue No.12 - December (1971 vol.20)
Modified Meggitt methods (pseudodivision methods) are suggested for evaluating logarithm, arctan, and square root. The modifications described here consist in restricting the magnitude of the pseudopartial remainsler such that the pseudoquotient assumes a form close to the minimal representation in the radix of choice. These methods will become useful for large-scale integrated system design.
Arctan, function evaluation logarithm, pseudodivision, square root.
