Number of decimal places in recorded data

[lauraalkhoury]

Hi everyone,

I am using the Write to Measurement File Express VI and every thing works well except for one thing. I have too many decimal places in my recorded data. I really only need 2 decimal places for my application. Is there a way I can fix this without having to open the file with Excel and format the numbers?

Just FYI I am writing dynamic data, the Write VI is configured for Text (.lvm) file format, and it is tab delimited.

Attached are two pictures: one of the spreadsheet of recorded data, and the other is my Write to Measurement Express VI.

Thanks!

Laura

Not with the express vi's

You CAN specify a format "%.2f" in write to spreadsheet file

Hi Laura,

As Jeff said, you cannot specify the format with the express VI you are using.  I would suggest taking a look at an example that ships with LabVIEW.  If you open the NI Example Finder (Help»Find Examples) and browse by task. Select the folder path Fundamentals»File Input and Output»Write to Text File.vi.  I have highlighted the part where you can format the numbers in the screen shot below.
