An Extended Arithmetic Package In many fields, for example algebraic number theory, arithmetic must be carried out to a degree of precision which exceeds the normal hardware capacity of most machines. In such cases, an extended arithmetic package provides a comprehensive and easy-to-use way of performing such arithmetic. Such a package was coded for the IBM 7090. In discussing the general problems associated with the design of an extended arithmetic package, specific reference is made to this program. CACM May, 1965 Blum, B. I.
