saving csv from excel loses decimal point precision
提问by LostLin
If I create a simple .csv file containing something like this:
如果我创建一个包含如下内容的简单 .csv 文件:
01/22/2013,3.14159265358979323846264338
and proceed to open it up in excel, the cell will show a rounded number i.e. 3.141592654
and the formula bar will show the whole value. However if I make some changes and save the csv file, or just save the original file as a different csv file, the file will only contain the rounded number 3.141592654
, causing me to lose some decimal point precision.
并继续在excel中打开它,单元格将显示一个四舍五入的数字,即3.141592654
公式栏将显示整个值。但是,如果我进行一些更改并保存 csv 文件,或者只是将原始文件另存为不同的 csv 文件,该文件将只包含四舍五入的数字3.141592654
,导致我失去一些小数点精度。
I am writing these files out via a vba macro. I have tried :
我正在通过 vba 宏写出这些文件。我试过了 :
ActiveWindow.DisplayFormulas=True
before the save command, and it works except it changes my date into a numeric format and I have not figured out a way to apply this format to only a range of cells. Is there some simple way to keep my numeric precision?
在保存命令之前,它的工作原理只是将我的日期更改为数字格式,而且我还没有想出一种方法可以将这种格式仅应用于一系列单元格。有没有一些简单的方法可以保持我的数字精度?

If you know which cells are going to be affected, try something like
如果您知道哪些细胞会受到影响,请尝试类似
Range("MYNUMBERS").NumberFormat = "#0.000000000000000"
