A language that supports arbitrary precision numbers with interactive
execution of statements.  There are some similarities in the syntax to
the C programming language.

A standard math library is available by command line option.  If
requested, the math library is defined before processing any files.
bc starts by processing code from all the files listed on the command
line in the order listed.  After all files have been processed, bc
reads from the standard input.  All code is executed as it is read.
(If a file contains a command to halt the processor, bc will never
read from the standard input.)

This version of bc contains several extensions beyond traditional bc
implementations and the POSIX draft standard.  Command line options
can cause these extensions to print a warning or to be rejected.  This
document describes the language accepted by this processor.
Extensions will be identified as such.
