There’s no such node yet. Although it should be relatively easy to do if you wrap the standard C++ [`atof`](http://www.cplusplus.com/reference/cstdlib/atof/) into a [new C++ node](https://xod.io/docs/guide/nodes-for-xod-in-cpp/). ---

And how can this solution look like? ---

hi, try these, it is an adaptation of another node, I do not remember what it is at this moment.

No use simulation, use upload to board
