有时候需要对一个特定的含有小数点的数字保留指定位数,比如"123.123600". 在数据库中以函数的形式实现如下: USE [数据库名称] GO /****** Object: UserDefinedFunction [dbo].[AvgLimit] Script Date: 2016/12/29 11:30:44 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ,),@numlimit int) ) As Begin
Private Sub textbox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles textbox1.KeyPress If e.KeyChar = Chr(8) Then Exit Sub If InStr(textbox1.Text, ".") = 0 Then textbox1.MaxLength = 12 Else text
import java.math.BigDecimal; import java.text.DecimalFormat; import java.text.NumberFormat; public class format { double f = 111231.5585; /** * BigDecimal */ public void m1() { BigDecimal bg = new Big
IF EXISTS ( SELECT * FROM sysobjects WHERE xtype = 'fn' AND name = 'fn_NumberFormat' ) BEGIN DROP FUNCTION [dbo].[fn_NumberFormat] END GO CREATE FUNCTION [dbo].[fn_NumberFormat] ( @number MONEY , @points INT ) ) AS BEGIN --2015年3月17日11:29:36 --201501
