2008-compatible system with the XSI (X/Open System Interfaces) option group.
Be aware that this
bc requires some items in C99 that are considered optional,
Since POSIX 2008 with XSI requires the existence of a C99 compiler as
POSIX and XSI-compatible system will have everything needed.

bc does not build out of the box on any
system besides Windows. If Windows binaries are needed, they can be found at

./configure.sh -O3 make
To only build
bc, use the following commands:
./configure.sh --disable-dc make
To only build
dc, use the following commands:
./configure.sh --disable-bc make
For debug builds, use the following commands in the root directory:
./configure.sh -g make
To install, use the following command:
dc will be installed in
/usr/local. For installing in
other locations, see the build manual.
bc is robust.
It is well-tested, fuzzed, and fully standards-compliant (though not certified)
bc. The math has been tested with 40+ million random problems, so
it is as correct as I can make it.
bc can be used as a drop-in replacement for any existing

bc. It is slightly slower on certain
operations and slightly faster on others. Full benchmark data are not yet

bc only has support for English (and US English) locales.
