Conversion string from a system unit to another

[dario1979]

Hi all i've a problem

i'm talking with an oscilloscope.

when i ask it some information like X or Y scale, it answers me a string (like 0.0016 to indicate 1.6m or 0.0000005 to indicate 500n).

I'm finding difficulties because the first string to number conversion cut me the number so i can't go on....

I want 2 number indicators:

1)  with the value with 3 digits;
2)  unit as an integer to connect to a ring array of constants (filled like mVolt,nVolt,pVolt ecc)

Can you help me?

Regards

Dario

Hi Dario,

you can set the formatting of your number indicators!
Maybe you try to use a format like '%3p' to show a number with 3 digits and SI unit...

You can also go this way: right-click your number indicator, select format&precision and set it to 3 'significant digits' and 'SI notation'

Hi Dario,

GerdW is right; you can both set your indicator formatting and choose the best suitable conversion function for you.

Below there's a simple example of conversion string/numeric (double) (It's in 7.1)

Hi Dario,

here's a picture of Fabio's vi (with small addition by me to demonstrate the number-to-string formatting):
