Format and Append

[cheyne]

Regarding the format and append VI, what does this %.;%f HZ; means? I saw it in most of the driver's VI. Please enlighten me if you know the meaning. Thanks

the %.; switches off the localized decimal separator, so it is always "." (and not "," like on some european computers.)

the %f formats a floating point number and the " HZ" outpust the string "<space>HZ".

Thus if the input is a DBL 5.0 , the formatted output string would be "5.000000 HZ" everywhere. (Without the %.; at the beginning, the output would be "5,000000 HZ" e.g. In Germany.)

Check the online help, especially the page labeled "Format Specifiers Syntax Elements". 🙂

Hi, Thanks for answering my question,

I have tried to take out the %.; but the output seems to be the same and nothing is change. So does it matter if I don put the %.;?

If you are in the US, you can leave it out.

However, if you ever plan to give your program to someone overseas, it might be safer to leave it in. It does not hurt anything!
