This version fixes an incompatibility with GNU bc:
The statement:
if (a > b) 1
was rejected, unless followed by "else 0".

This is an implementation of POSIX bc that implements GNU bc extensions, as
|
|
well as the period (".") extension for the BSD flavor of bc.
|
|
|
|
bc is an arbitrary precision numeric processing language. Its syntax is
|
|
similar to C but differs in many substantial areas. It supports interactive
|
|
execution of statements. The bc utility is included in the POSIX 1003.1-2008
|
|
standard.
|
|
|
|
This bc also includes an implementation of dc in the same binary, accessible
|
|
via a symbolic link, which implements all FreeBSD and GNU extensions. If a
|
|
single dc binary is desired, bc can be copied and renamed to dc.
|
|
|
|
The "!" command is omitted; I believe that it poses security concerns and
|
|
that such functionality is unnecessary.
