-Calc is an interactive calculator which provides for easy large
-numeric calculations, 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, the following line can be input:
-
- 3 * (4 + 1)
-
-and the calculator will print 15.
-
-The special '.' symbol (called dot), represents the result of the last
-command expression, if any. This is of great use when a series of
-partial results are calculated, or when the output mode is changed and
-the last result needs to be redisplayed. For example, the above
-result can be doubled by typing:
-
- . * 2
-
-and the calculator will print 30.
-
-For more complex calculations, variables can be used to save the
-intermediate results. For example, the result of adding 7 to the
-previous result can be saved by typing:
-
- old = . + 7
-
-Functions can be used in expressions. There are a great number of
-pre-defined functions. For example, the following will calculate the
-factorial of the value of 'old':
-
- fact(old)
-
-and the calculator prints 13763753091226345046315979581580902400000000.
-Notice that numbers can be very large. (There is a practical limit
-of several thousand digits before calculations become too slow.)
-
-The calculator can calculate transcendental functions, and accept and
-display numbers in real or exponential format. For example, typing:
-
- config("display", 50)
- epsilon(1e-50)
- sin(1)
-
-prints "~.84147098480789650665250232163029899962256306079837".
-
-The calculator also knows about complex numbers, so that typing:
-
- (2+3i) * (4-3i)
-
-prints "17+6i".
