formata string A%f

[netra]

Hi,

I am new to LabVIEW and this is kind of a basic question.

I am trying to understand a code and I am supposed to modify it to suite our application. So here, I've got 'Scan from String' and to its 'Format String' terminal. 'A%f'

Now I know what %f is..but I don't understand what 'A' stands for.

Thanks in advance!

It appears that your program is looking for the literal string "A" before a floating-point number.

hi jcarmody,

Thank you for such a quick response!

So in order to get say 8 digits and 3 after the decimal point, I should write '%8.3f' right?

Thanks in advance!

You should probably use "%.3f".  The width is very specific.  So if you might not have exactly 8 characters in the number you will not get the right number.  Be sure to look in the help for the Format Specifier Syntax article.
