LabVIEW stores floating point numbers in IEEE 754 format. Under the File I/O>Binary File VIs there is Read From SGL File.vi that should work if they were stored with 32-bit IEEE single-precision format. if they were stored with 64-bit precision, you can modify the VI by changing all of the data types from SGL to DBL. If you need the numbers outputed to a text file, you could take the VI's output and wire it to the Write To Spreadsheet File function.
