Algorithm 693: a FORTRAN package for floating-point multiple-precision arithmetic
Algorithm 693: a FORTRAN package for floating-point multiple-precision arithmetic is a scholarly work, published in 1991 in ''ACM Transactions on Mathematical Software''. The main subjects of the publication include single-precision floating-point format, double-precision floating-point format, point, digital signal processing, saturation arithmetic, arithmetic, arbitrary-precision arithmetic, computer science, computational science, elementary function, Fortran, elliptic curve cryptography, parallel computing, floating point, mathematics, and algorithm. Results are almost always correctly rounded, and due to improved algorithms used for elementary functions, reasonable efficiency is obtained..
