how can i change a String variable, coming from an entity parse to Float.
You can use the parse and format float calls documented here to convert to and from floats respectively.
Hope this helps
Yes you would need a microflow to do so.
In the image beneath you can see how you can parse a String parameter to a Float variable. If you have any questions feel free to ask them.
P.S.: I would recommend using a Decimal instead of a Float as Floats are deprecated.
Thanks for answer.
But where can i parse it and how to do this (in an microflow?)
