# concalc(1)

console calculator

## 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

- square 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 executing 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
