# Finite Fields Aritmetics in raku

```raku

use FiniteField;

my $*modulus = 13;

say 10 + 5;  # 2

say 10 / 3;  # 12  (3*12 = 36 = 13*2 + 10)

```

## Notes

   

  * The dynamic variable `$*modulus` must be defined before calling any overloaded operator,

  otherwise the program will crash (no exception is handled so far).

  * Modular division will not check for primality of modulus or any other requirements.

  * Define a modulus for each lexical scopes you import the module in.

  * Althouh the name of this repo is using a plural, the name of the module

  itself is singular, because you only use one finite field at a time.

  * The main purpose of this module is to make writing cryptographic code easier.
