Starting approximations for square root calculation on IBM system /360
Abstract
Several starting approximations for square root calculation by Newton's method are presented in a form to facilitate their use in IBM System/360 square root routines. These approximations include several for the range [1/16, 1], which is the interval of primary interest on IBM System/360. © 1966, ACM. All rights reserved.
