string into data

[hhaoo]

I have a 2-D array of strings, like 2E-7, 3.4E-9; 2.1E-7, 3.3E-9;...........I want to conver them into data. I found a "strip/xxx" vi, however, it can only give me 0.00, 0.00. What should I do in order to keep the same value without any truncation?

THanks

You only need to use  a Frac/exp string to number function (in the string sub-palette), as in the attached vi.

I did exactly the same as shown in your attached file. However, the numbers were all zeros after I saved the data. My guess for that is: LV truncates everything else after they save the first three digits of the data. Do you know how to avoid that?

Check the display format : the digits are probably still there, but not displayed. Right click and go to

"Format & Precision". Select either Automatic formating or Scientific, and see...

Upon reading your reply, you said that the numbers were all zeroes after saving the data. Beware of the file saving functions, and specially of the "save to spreadsheet" vi, since it save the data as floating points with only 3 digits. If this is your case, change the optional input format specifier to %#g or %#e, where g and e stand for automatic and exponential formating , respectively, and # is the number of digits you want after tha decimal separator.

Thanks a lot. I fixed the problem already.
