Number.prototype.formatMoney = function(c, d = '.', t = ','){
	var n = this,
	    c = isNaN(c = Math.abs(c)) ? 2 : c,
	    d = d == undefined ? "." : d,
	    t = t == undefined ? "," : t,
	    s = n < 0 ? "-" : "",
	    i = String(parseInt(n = Math.abs(Number(n) || 0).toFixed(c))),
	    j = (j = i.length) > 3 ? j % 3 : 0;
	   return s + (j ? i.substr(0, j) + t : "") + i.substr(j).replace(/(\d{3})(?=\d)/g, "$1" + t) + (c ? d + Math.abs(n - i).toFixed(c).slice(2) : "");
