网银转帐时, 填写金额后下方出现的汉字金额, 这是Java下的实现.

    public static String toRMB(double money) {
        char[] s1 = {'零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'};
        char[] s4 = {'分', '角', '元', '拾', '佰', '仟', '万', '拾', '佰', '仟', '亿', '拾', '佰', '仟', '万'};
        String str = String.valueOf(Math.round(money * 100 + 0.00001));
        String result = "";

        boolean zeroFlag = false;
        for (int i = 0; i < str.length(); i++) {
            int n = str.charAt(i) - '0';
            int level = str.length() - i - 1;
            if (n == 0) {
                zeroFlag = true;
                if (level % 4 == 2)
                    result += "" + s4[level];
            } else {
                if (zeroFlag) {
                    result += "零";
                    zeroFlag = false;
                }
                result += "" + s1[n] + s4[level];
            }
        }

        return result.replaceAll("亿万", "亿").replaceAll("元$", "元整");
    }
