Parse letters from numbers

[mshask]

Hi, I have to parse the letters out of a string to just get the numbers. I have four cases (just using filler numbers for this), so I have-

Vbatt: 0.15V

Ichgin: 0.15A

Ichgin: 0.15A

Ibatt: 0.15A

and I want just 0.15 as an output string. How do I approach this for all different cases?

Thanks in advance

For each line, parse the substring after ":"

You can do it with a single Scan from String.  Read the Detailed Help for this function (drop the function on the Block Diagram, select it, and choose Help).

It wasn't clear if "I have four cases" means that each scan is one of the four or if we get the entire four-line string at once, differing only in the numerics between successive scans.

The following regular expression would work:

([\d\.]+)

If you want to also extract the units, you could use the expression:

([\d\.]+)(\w)
