Reduce redundant work
bcThis is an implementation of POSIX bc that implements GNU bc extensions, as well as the period (.) extension for the BSD bc.
This bc also includes an implementation of dc in the same binary, which includes all FreeBSD and GNU extensions. However, it does not have the ! command; the author does not want to deal with the security implications, and it is unnecessary in this day of full-featured shells.
This bc is Free and Open Source Software (FOSS). It is licensed under the BSD 0-clause License.
To build, use the following commands:
make [bc|dc] make install
This bc supports CC, CFLAGS, CPPFLAGS, LDFLAGS, LDLIBS, PREFIX, and DESTDIR make variables. Users can also create a file named config.mak in the root directory to control make.
There is also a make help command to list all targets and options.
This bc is in beta stage. It has been well-tested and fuzzed, but has not yet been proven in the wild.
This bc is written in pure ISO C99.
This bc uses the commit message guidelines laid out in this blog post.
This bc uses semantic versioning.
