本文介绍了VB.NET将Double Value转换为String =精度损失的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
Dim值= 9.729000000000001
转换成字符串时,我得到这个:
value.tostring()9.729
我尝试添加格式: / p>
value.tostring(0.00000000000000)
但它没有起作用(我输了1)。
如何保留所有的数字? >
解决方案
尝试这个
Dim值As Double = 9.729000000000001
Dim strText As String = value.ToString(G17)
或这个
Dim值As Double = 9.72900000000000 1
Dim strText As String = value.ToString(R)
Hello I have a double value like this in VB.NET:
Dim value = 9.729000000000001
When converting to string, I get this:
value.tostring() "9.729"
I try to add formatting:
value.tostring("0.00000000000000")
But it did not work (I lose the ending 1).
How can I keep all of my digits?
解决方案
This is documented here and here
Try this
Dim value As Double = 9.729000000000001
Dim strText As String = value.ToString("G17")
Or this
Dim value As Double = 9.729000000000001
Dim strText As String = value.ToString("R")
