Calc is an interactive calculator which provides for easy large
|
|
numeric caluclations, but which also can be easily programmed for
|
|
difficult or long calculations. It can accept a command line
|
|
argument, in which case it executes that single command and exits.
|
|
Otherwise it enters interactive mode. In this mode, it accepts
|
|
commands one at a time, processes them, and displays the answers.
|
|
In the simplest case, commands are simply expressions which are
|
|
evaluated. For example, he following line can be input:
|
|
> 3 * (4 + 1)
|
|
and the calculator will print 15.
|
|
|
|
Commands are statements in a C-like language, where each input line
|
|
is treated as the body of a procedure. Thus he copmmand line can
|
|
contain variable declarations, expressions, labels, conditional
|
|
tests, and loops. Assignments to any variable name will automatically
|
|
define that name as a global variable.
|
|
|
|
For more information on the program, run 'calc help help'.
