Extracting Numbers from file

Extracting Numbers from file

Extracting Numbers from file

(OP)
Hi, i collected Data from a meter and saved it as a *.txt file. Now, when i try to plot that data, i use the read character from function and connect it to extract numbers vi in the string library in the general folder. However, i am having trouble plotting data with the E (exponential). Ex. 1.23e-05 is out put as 2 separate numbers, 1.23 and -5, this is think is due to the "regular expression" of the MATCH PATTERN function in the extract numbers.vi .. So if anyone knows anything about how to edit this regular expression so that the exponential function isnt broken, please help me out, any resources in this regard will be helpful too. THANKS!

RE: Extracting Numbers from file

You might try one of two things: 1) use a "Read From Spreadsheet File" vi to try to read in your data file in numerical form or 2) use the "Fract/Exp String to Number" vi to convert the exponential string to number.
