	let p = n.indexOf('.');
	
	if (p >= 0) n = n.substring(0, p) + n.substr(p + 1, 2);

	unit = unit.substr(unit.length - n.length);
	for (let i = 0; i < n.length; i++) str += '零壹贰叁肆伍陆柒捌玖'.charAt(n.charAt(i)) + unit.charAt(i);

	return str.replace(/零(仟|佰|拾|角)/g, "零").replace(/(零)+/g, "零").replace(/零(万|亿|圆)/g, "$1").replace(/(亿)万|壹(拾)/g, "$1$2").replace(/^圆零?|零分/g, "").replace(/圆$/g, "圆整");
