Many people mistakenly treat the math. Round function as a rounding function, and the result is often incorrect. In fact, math. Round adopts the internationally accepted banker rounding method.
Banker's rounding (banker rounding)AlgorithmThat is, four homes, six homes, and five shopping cart. In fact, this is also the IEEE Standard for rounding. Therefore, all IEEE-compliant languages should adopt this al
Math. Round is used to round the value by the specified small number,Is not.When this type of rounding is performed, It is rounded up to the nearest or rounded up to five.
In fact, in VB, VBScript, C #, J #, the number of round functions in the T-SQL is the banker's rounding algorithm, that is, four homes, six homes, five homes, and five shopping carnivals. In
Samba is running at the server or domain level
Username map =/etc/samba/smbusers # account ing File
Then, create the main directory of each user
[Homes]
Comment = user's home directories
Browseable = No
Valid users = % s
Writable = Yes
In this way, the most basic functions are met. If you still need directories with other permissions, you can continue to add them.

Introduction
Wireless Home network is becoming the first choice for data service distribution in the family. The price of 802.11b is comparable to that of Wired solutions, and interconnection between old and new families can be achieved without any connection. It is a natural choice for users who want to build networks in their homes. The enterpri

Second, the enterprise-level market is also the base camp of Microsoft. If enterprise users cannot find a system that can replace Windows, they will not be rashly moved. After all, large-scale device replacement is not only expensive, in addition, the learning cost of the new system is also relatively high.
Third, due to the high popularity of Windows, many professional and productivity software are willing to settle their homes h

Comment: Rounding the number to retain two decimal placesAket 6799 0:46:18It is not necessary to rounding the number into and keep two decimal places. Use the following code.To directly use the roundto function, you must add math to uses.Roundto (1.245,-2); = 1.25
It should be noted that the old Delphi version of the round function uses four homes and six inputs. In every five, the first entry is an odd number, and the last entry is an even number, ex
