NAME

       concalc - console calculator

SYNOPSIS

       concalc [options] "expression"

       concalc -m script "path"

DESCRIPTION

       concalc	calculates  the given input term and returns the result as text.  Please use will have problems with the shell interpretor. If you
       give concalc more than one expression, all expression will be put together.

CALCULATION SYNTAX

       standard calculations
	      2*(3+4/9)^3

       standard operations
	      + - * / ^ % sin cos tan asin acos atan sinh cosh tanh asinh acosh atanh ln log & | ! && || ~ >> << x rnd sqrt curt root integ d/dx

       sqare root and cubic root
	      sqrt12 curt8

       trigonometric functions and logarithms
	      sin3.64+ln5

       other roots
	      fourth root of nine: 4root9

       differential calculation
	      differential calculation of 2x^2-3x+3 at x=9: d/dx(2x^2-3x+3,9)

       integration
	      integration of sinx+cosx between -1 and 3.2: integ(sinx+cosx,-1,3.2)

       set variables
	      save the result of a calculation in variable A: 12*45/2->A

       recall variables
	      multiply the saved value with 2: A*2

       use last result
	      The last result is saved in the answer memory: ans+1

CONSTANTS

       e      euler constant

       pi     pi; example: sin(pi/2)

NUMBERS

       standard
	      12.34

       with exponent
	      12.23e-5

       complex
	      12i-5

OPTIONS

       -o, --output [output length]
	      The argument is a number between 2 and the maximal possible output length (normally 18).

       -m, --mode [calculator mode]
	      The mode can be std (default, normal scientific calculatons), base (for logic functions and base-n calculatons) or script (for  exe-
	      cuting scripts). In scripting mode, the last argument must be the path to the script file.

       -c, --complex
	      This option enables complex numbers for the calculation. They are switched off by default.

       -b, --base [calculator base]
	      The  argument  must  be one of hex (hexadecimal), dec (decimal, default), oct (octal) and bin (binary). This option can only be used
	      when -m base is set.

       -a, --angle [angle type]
	      The argument must be one of deg (degrees), rad (radiant), gra (grade).

       -v, --version
	      Output the version of Concalc.

       -h, --help
	      Outputs a short help.

SCRIPTING

       The script interpreter of calc uses a C-like programming syntax.  The following command are supported.

       if expression

	      if(condition)

		command for condition true;

	      else command for condition false;

       while loop

	      while(condition)

		command that is run while condition is true;

       for loop

	      for(initialisation; condition; count-command)
		command that is run while condition is true;

       print command

	      print( output to print out );

       getline command

	      getline; // read a text line from stdin and returns this text

       getkey command

	      getkey; // return the key pressed by the user
		      // blocks until the user presses any key

       keystate command

	      keystate; // returns the key pressed by the user or 0 if no key was pressed
			// nonblocking

       sleep command

	      sleep( time in microseconds ); //Script is stops for the given time

       compare operators

	      ==, != equal, unequal

	      >=, <=, >, < greather or equal, less or equal, greather, less

       set operators

	      -> calculator set operator

	      = C-like set operator

       type converting

	      (float) floating point value

	      (int) integer value

	      (string) text value

	      (bool) boolean value
