String to Number Conversion

[Rshah31]

I am getting a string measurement "-2.927184E-04" from the multimeter. I want to convert to the number.  

I am using "Fract/Exp String To Number," but I could not get a number 

 

Please suggest me any solution

Hi Rahah,

remove the quotation marks...

Which DMM do you use that sends data within quotation marks?

I personally prefer the scan from string vi to have more control on the format. 

the format string allow to define the decimal point ( %.; )  

Just in case you run into the problem, that a device is using the comma and your local setting is point.  Assuming that the string(or device) always use the same decimal point ...

edit: and it would work with the quotation marks 😉  

or generally speaking with nearly all type of strings and data to exstract
