Description

A package of FORTRAN codes has been developed for certain multiple precision integer operations. These operations include basic arithmetic, modular exponentiation, and conversion of numbers to and from decimal representation. Reliability of the results is maintained by cross-checking both the lengths of internal working storage arrays against the requirements of the operations, and the size and sign of the internal representation of the digits. 10 figures.
