mcalc

mcalc is a graphical multi-precision calculator, which focus on Number Theory.

It is a graphical front-end to GMP.

Screenshot:

If the result is longer than 34 digits, it will be displayed in the terminal.

Usage

Some of the less obvious keys:

"Fn" calculates the nth fibonacci number

"!" calculates the factorial

"#" calculates the primorial

"np" calculates the next prime number

"p?" primality test

Compile and run:

Dependencies:

In order to compile mcalc, you will need these two libraries installed:

• GLFW (https://www.glfw.org/)

• GMP (https://gmplib.org/).

On Linux Mint, install the dependencies using:

sudo apt install libglfw-dev libgmp-dev

Campilation command on UNIX-like:

make

Always launch it from a terminal:

./mcalc

Example: calculate the largest known prime number:

Advantages of using mcalc are the speed and ease of use (when compared to programming tools like python or bc).

List of GMP functions wrapped up so far

Currently, the following functions are available to use directly:

• mpz_mul();
• mpz_div();
• mpz_sub();
• mpz_add();
• mpz_pow_ui();
• mpz_fac_ui();
• mpz_probab_prime_p();
• mpz_nextprime();
• mpz_sqrt();
• mpz_primorial_ui().
• mpz_fib_ui();

Feel free to place requests for more functions in the "issues" section :P
