SYNTAX
bc [ -hlwsqv ] [long-options] [ file ... ]
DESCRIPTION
bc is 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 proces
sor, 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.

-i, --interactive

-l, --mathlib

-w, --warn
