This is GNU bc version 1.07.1. (And dc version 1.4.1) Changes in bc from 1.07 to 1.07.1. Fixed ibase extension causing problems for read() Fixed parallel make problem. Changes in dc 1.4 to 1.4.1. Fixed dc "Q" comanmd bug. Changes in bc from 1.06 to 1.07. Added void functions. Bug fixes: fixes bug in load_code introduced by mathlib string storage in 1.06. fix to get long options working. signal code clean-up. fixed a bug in the AVL tree routines. fixed math library to work properly when called with ibase not 10. fixed a symbol table bug when using more than 32 names. removed a double free. Added base 17 to 36 for ibase. Fixed some memory leaks. Various small tweaks and doc bug fixes. Changes in dc from 1.3 to 1.4: Recognize and handle tail recursion. Add 'r' and 'R' commands for stack manipulation. Finally fix dc to trap interrupts, like the documentation has said it should: aborts any executing macros, but does not exit the program. Bug fixes. Miscellaneous code clean-up. Changed to detect directories and generate errors. Detects and reports on any output errors; exits non-success. Changes in dc from 1.2 to 1.3: Minor bug fixes. New multiply algorithm of bc. Changes in bc from 1.05 to 1.06: New multiply algoirthm and many other changes in lib/number.c Function size now done dynamically. Function syntax in non-posix mode allows newlines in more places. Bug fixes: improved computation of j(n,x). enables readline only if interactive. for statment bug fixed. use int instead of char for readline char counts. improved cosine accuracy. Changes in dc from 1.1 to 1.2: added !< != !> commands arrays now stack output is now line buffered, provided setvbuf() is available fixed known bugs in 'q', 'Q', 'a' commands, '-f' command-line option, and documentation changed the 'P' command's behavior on a numeric argument: due to popular demand it now does the equivalent of 'aP' (for small values) added new 'n' command to do what the old 'P' command did Changes in bc from 1.04 to 1.05: Solaris makes work better. bug fixes stdout now always does line buffering. sqrt bug fixed for small numbers. readline (if support is compiled in) is enabled only for interactive executions of bc. This is GNU bc version 1.04. (And dc version 1.1) Changes from 1.03 reorganization of source tree use of automake new commands for dc (|, ~, r, a) new command line options for dc fixed infinite loop in sqrt in bc fixed an I/O bug in bc made bc conform to POSIX for array parameters added long option support for bc new commandline options for bc (-q) added support for readline to bc (use configure --with-readline) command line argumens can now be taken from an environment variable Changes from 1.02 minor bug fixes in bc. addition of Ken Pizzini's dc program that uses the GNU bc arbitrary precision arithmetic routines. Changes from 1.01 minor bug fixes.
