Hello ninskaya,
do you really use "Write File"? This should save your numbers in binary code and this way you don't loose any accuracy. You should only tell "Read File" the same datatype...
You could also use "Write/Read Spreadsheet File" and give those functions a proper format string. In your cases this might be "%.5f".
