function getRandomNumber (min, max, fixed) {
    var num = 0;

    if (min > max) {
        return ( -1 );
    }
    if (min == max) {
        return ( min );
    }

    if (fixed !== 0)
        num = parseFloat(min + (Math.random() * (max - min))).toFixed(fixed);
    else
        num = parseInt(min + (Math.random() * (max - min)));

    return num;
}
