bc

bc is an arbitrary precision numeric processing language. Syntax is similar to C, but differs in many substantial areas. It supports interactive execution of statements. bc is a utility included in the POSIX P1003.2/D11 draft standard.

Since the POSIX document does not specify how bc must be implemented, this version does not use the historical method of having bc be a compiler for the dc calculator. This version has a single executable that both compiles the language and runs the resulting `byte code'. The byte code is not the dc language.

Downloading bc

bc can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/bc/ (via HTTP) and ftp://ftp.gnu.org/gnu/bc/ (via FTP). It can also be found on the GNU mirrors; please use a mirror if possible.

Documentation

Online Manual is available at www.gnu.org/software/bc/manual/, as well as one for dc. info bc or man bc, or by looking at /usr/doc/bc/, /usr/local/doc/bc/, or similar directories on your system. A brief summary is available by running bc --help.
