我有这种形式更新数据库中的记录。我应该输入十进制数字，它完成它的工作并更新数据库。问题是它只能读取整个数字。在数据库上设置十进制但仍然只读取整数
实施例：
2.35（更新值变为2）
我也没有设置sickleave和vacationleave的类型在我的数据库为十进制。可能是什么问题？我做错了吗？
这里是我的代码：
<?php
/*
Allows the user to both create new records and edit existing records
*/
// connect to the database
include("connect-db.php");
// creates the new/edit record form
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($fullname = '', $username ='', $error = '', $id = '', $email = '', $address = '', $contact = '', $gender = '', $password = '', $user_levels = '', $date = '', $picture = '', $sickleave = '', $vacationleave = '')
{ ?>
