PHPDocs incorrect

[MrJmpl3]

Using PHPStorm, I saw the PHPDocs are incorrect, for example:

    /**
     * Formatea y ejecuta la función conversora con formato para facturación
     *
     * @param $number número a convertir
     * @param $decimals número de puntos decimales
     * @param $currency nombre de moneda
     * @return void
     */

In PHPDocs, that mean: $number is a type of "número".

To fix, I recommend add a type of variable in the docs or add mixed instead.

PHPDocs updated with v2.0.1 release.
