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

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
