This directory is deprecated. Please see ../arithmetic-5/README for information about which arithmetic books to use. Original comments (for this deprecated directory): This directory was written by Robert Krug, based in part on the arithmetic/ directory but with many changes that make this potentially more useful in a number of circumstances. Contents: The directory pass1 should be of no concern to the user. The reasons for its existence are historical rather than practical. The book meta/top.lisp is the top-level arithmetic book to use. The book floor-mod/floor-mod.lisp is the beginning of a library about floor and mod. It has not received as much attention as it should have, but should still be useful.
