concalc - console calculator
concalc [options] "expression" concalc -m script "path"
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.

-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.
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
