description="
An arbitrary precision numeric processing language.

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.
