  # Finite Fields Aritmetics in 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.
