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.
|CMUCL||All tests pass|
|SBCL||All tests pass|
|CCL||All tests pass except for two, which are probably bugs in CCL|
|Clisp||All tests pass, but clisp doesn't support signed floating-point zeros|
|Allegro||Working, but not recently tested|
Note that development is primarily done using CMUCL.
