从表到CSV文件打印小数值

Question

//Java代码以CSV为CSV使用FileWriter。

Java Code :
FileWriter fileWriterForCsv;
fileWriterForCsv.append(4.500);
fileWriterForCsv.append(",");
fileWriterForCsv.append("Mani");
fileWriterForCsv.append(",");
fileWriterForCsv.append("March");

//以下提到的CSV文件的内容 生成的CSV ______________

Actual Result : 4.5,Mani,March
Expected Result : 4.500,Mani,March
Please let me know whether i need to change the java code??  or how to proceed to get the expected result as above mentioned

还尝试将CSV模板中的文本类型更改为文本。没有得到预期的结果。

尝试格式化数字输出。这应该在末尾用CRLF写整个线。

fileWriterForCsv.format("%.3f,%s,%s%n", 4.5, "Mani", "March");
