Here is a simple answer

The hard part is format of the data in your file and converting it correctly from a string to a number.

Do you have complete control over how the data is stored in your file?

Is there any chance in the future the format of the data string in the file could change?

Also look at Configuration file (.ini files) in LabVIEW

i am facing problems while reading floating point numbers what modifications is to be done in the regular expression input( X=(\d+) of the match regular expression.

This is a VI I use to parse floats

It will go through a string and pull out any and all numbers that is finds in order.

The simplest method is to use the Scan From String. The format string has to be exactly correct for the expected string.

It is not very flexible. If one thing does not match, you get all zeros

So again, the method you use depends a lot on the format of the string in your file.
