Welcome to Oct, a portable implementation of quad-double numbers
Oct is a portable Lisp implementation of quad-double arithmetic. This gives about 65 digits of precision. Quad-double arithmetic uses four double-float numbers to represent an extended precision number.
The implementation is modeled on the quad-double package by Yozo Hida. That package is in C++, but we have translated parts of it and extended it to use Lisp. The intent is to provide all of the CL arithmetic functions with a quad-double implementation.
This package has been tested with CMUCL, SBCL, Clisp, and Allegro. All tests pass. Note that development is primarily done using CMUCL.
To obtain the sources, you will have to clone the repository at git://common-lisp.net/projects/oct/oct.git or http://common-lisp.net/r/projects/oct/oct.git.
