Scan from String , can't get number from string

[dabrowskp]

hello 

I've just started lerning LabView and i've got problem that I can't overcame. Topic is simple , I have string ( let say exactly like in screen shot ) 14.12 and I would like to change it to a number because it will be send to graph. As you see after scanning from string I get Output 14 , and remaining string .12  😞 I need Output = 14.12   I've serched on this forum topics conected with this mater but I can't find answer. Mayby someone can help me 🙂

Well, in LabVIEW 2016 32-bit, I get 14.12 as Output 1 and nothing in Remaining String.  Some thoughts:

• Is your PC set to use the comma (",") as the decimal indicator (i.e. 14,12)?  This would definitely produce the output you are seeing.  Try changing the input string to 14,12 and see what happens ... 
• You can specify whether a Comma or Period is the decimal separator.  To specify the Period, start the Format Specifier with "%.;".  You can read more about this by reading the Help for Scan from String and following the links to Format Specifier Syntax.
• This could be a bug, but it hardly seems reasonable that this would escape even the shorter Development/Testing time for LabVIEW 2017 (not to mention that it has been in Users hands for almost 6 months).

Looking at the front panel shown in 2.jpg, this is definitely the case.

OP, use "%.;%f" as your format string.  The "%.;" forces the use of the period as the decimal separator.

Tools options environment has a checkbox to use some stem decimal seperater.  Make sure it is checked.  If it is.  You should not need to add the %,; in scan from string.

Hi Jeff,

while I use this setting from time to time too I still advise NOT to set this checkmark!

Users get easily annoyed/distracted when the LabVIEW-written tool is not following their regional settings…

Actually I was right and wrong

Read too fast.  The checkbox is set by default to use statement settings.  crossrulz pointed out that the OP apparently has a comma decimal seperater so to correctly scan nn.dd the %.;%f is needed.

Guys you are the best 🙂 you made my day 🙂

I haven't thought abaut that because I have been working on this project for a while and elier everything was working.  Probaply this problem is all my fault, I remember that I have instaled a few updates  and probably my regional setings have been changed.

Thanks again 🙂 

Best regards
