sprintf does not work with float
This seems to be a long standing problem with Arduino "C"
Numerous functions to act as a substitute can be found via a google search for this, however none of them seems to work either correctly or at all.
Does anyone know of a functional (preferably clean) solution?
If you have used something that works, an example would also be helpful.
Add this above setup
It will force the compiler to link floating point support for printf and scanf.
