Rounding
Select round (83.124, 2) as t from jqdltb

The question is, how does one turn into five homes and six homes?
The following is a rounding method:
Use the int function and add 0.005, then * 100, and then/100
As follows:
1. Install the NFS server and client:
Sudo apt-Get install nfs-kernel-server nfs-common Portmap
(2) sudo dpkg-reconfigure Portmap
Select "no" after running"
3. Configure the Mount directory and permissions

Sudo apt-get install sambaIf you get an error, you'll need to execute sudo apt-get update before re-executing sudo apt-get install sambaOnce the installation is complete, the Samba service is installed, and some basic tools are not installed, so you need to install the Samba support tool:sudo apt-get install samba-common-bin(Note: This step is very important, if this does not install will cause a tool like smbpasswd not to be installed, the latter will not be

If necessary, the interface can define a method to set and return a reference to the home. This role is typically implemented by a Java abstract class or Java interface.

or pass the request to the other person. As the specific processor holds references to the homes, the specific processor can access the homes if necessary.There is no extends inheritance concept in the strict sense of JS (before ES6), so the following code does not emulate the abstract class, only the specific processing class is implemented in the code.Usage scenario: In a shopping mall, in 51 to do an ac

Each node of the chain can be flexibly split and re-reorganized.Responsibility Chain ModelEnables multiple objects to have the opportunity to process the request, thereby avoiding the coupling between the sender and the recipient of the request, connecting the object to a chain, and passing the request along the chain until an object has process
The functionality of Samba is simple enough to make sharing between Linux and Windows possible. and using Samba to build a file server is not only more powerful than windows, but also fast and safe to access. Samba server has so many advantages, it seems that learning to build samba is the mission of network management.
