Control number of digits using format function

Solved!
Go to solution

Hello,

Please, I am trying to control the number of digits using format function and Format Specifier.

I acquired data using data acquisition. I got a number such as 1654.1876872. I want to get only two digits after comma such as 1654.18

 

I attached sample of the Vi which I tried but it's not working correctly

 

Thanks

Try "%.02f" for the format string.

Read the detailed help for that function.  You have nothing wired into value.  Your "value" is a string you wired into the prepend string input.  If your "value" is a string, you need to convert it to a number and back to a string.

 

Format Into String is much more commonly used than Format into Value.  For one, it lets you format multiple values into a single string if you need to.
