An example of creating a package

var math_shared = require('./math_shared.js');

function _fibo(count, counter, first, second) {
    if (count == 0) {
        return 0;
    }
    counter = counter || 1;
    first = first || 1;
    second = second || 2;

    var result = first + second;
    if (counter == count) {
        return result;
    }
    return _fibo(count, ++counter, second, result);
}



function multiply(x, y) {
    math_shared.binary_operation(
        x, y, function (_x, _y) { return x * y });
}

function divide(x, y) {
    math_shared.binary_operation(
        x, y, function (_x, _y) { return x / y });
}

function fibo(n) {
    math_shared.unary_operation(n, _fibo);
}

module.exports = {
    multiplication: multiply,
    division: divide,
    fibonnaci: fibo
