Add method for getting the continued fraction of an object.

Source:

/*
* Converse a fraction to a continued fraction
* @param {Number} a - numerator
* @param {Number} b - denominator
* @param {Number} limit - max number of elements returned.
* @return {Array} array of numbers
*/
var fractionToContinuedFraction = function (a, b, limit) {
    limit = limit || 1e3;
    var arr = [];
    a = +a;
    b = +b;
    while (0 < limit-- && a && b && (a !== 1 || a / b !== 1)) {
        arr.push( Math.floor( a/b ) );
        a %= b;
        tmp = b;
        b = a;
        a = tmp;
    }
    return arr;
}

Bug:

• Add condition for 0 and Infinity.

Does the opposite.

var continuedFractionToFraction = function (arr) {
    if(typeof arr !== "object"){
        return null;
    }
    var a = 1,
    b = 1,
    tmp,
    i = arr.length;
    while(i--){
        a += b * arr[i];
        tmp = b;
        b = a;
        a = tmp;
    }
    return [a, b];
};

Need to add unit tests. There a bug in the code but will check it out later.
