四舍五入到9 [英] rounding to 9's
问题描述
我正在尝试将我的货币字符串舍入到9结束。这是一个
定价应用程序。
这是我的功能'' m用于获取货币项目：
FormatCurrency（BoxCost ,,,, TriState.True）
如果项目是41.87我想要申请把它带到41.89
如果一个项目是41.84我希望应用程序舍入到41.79
有谁知道我怎么做这个？

您必须手动完成 - 只需解析小数后的第二位数字，然后相应地调整值。
谢谢，

You would have to do it manually - just parse the second digit after
the decimal and adjust the value accordingly.
Thanks,

嗨Jonathan -
您是否尝试过四舍五入到最近的十分之一并减去一个
hundreth？
将myVal变为双倍
myVal = 41.87
myVal = Math.Round（myVal，1） - 0.01
Debug.WriteLine（myVal）''返回41.89
myVal = 41.84
myVal = Math.Round（myVal，1） - 0.01
Debug.WriteLine（myVal）''返回41.79
....有时最简单的方法效果最好。
快乐编码，

Hi Jonathan -
Have you tried rounding to the nearest tenth and subtracting one
hundreth?
Dim myVal As Double
myVal = 41.87
myVal = Math.Round(myVal, 1) - 0.01
Debug.WriteLine(myVal) ''Returns 41.89
myVal = 41.84
myVal = Math.Round(myVal, 1) - 0.01
Debug.WriteLine(myVal) ''Returns 41.79
....sometimes the simplest approaches work the best.
Happy Coding,
-Mark
