 Formatstring in 'Scan from String'

i try to format a string (example 4.241) to a number, which looks same
(4.241). I do that with Scan from string, but without any Formatstring
he returns 4,00.
I havent any idea how these Formatstrings work, can someone please
post me the correct string?

Your system is set to use the comma as decimal separator and the the
scan stops at the point in "4.241" giving 4,00. Set the format string
to specify the decimal separator e.g. "%.;%f"

There is some help for the format string, it's just a bit hard to
find, if memory serves.  I just looked, and it's very obscure indeed.
You have to go to the labview user manual, which you can get to by
going to the help from anything that uses a format string (I used "to
Spreadsheet String").  You will get a link to the User Manual (PDF).
The information is somewhere in Chapter 9, but the help file doesn't
give really good instructions on finding the information in Chapter

The useage of the format string is actually pretty simple.  Once you
learn the rules, you won't have any trouble.

Good luck.

Labview uses standard ANSI "C" (programming language) format strings
in Scan From String etc.  It also uses a subset of Regular Expression
pattern matching in the Match Pattern string function.  Any standard C
programming reference will give you lots of examples of format
strings.  GH
