Set float or double value to NextionText?

[fedorenkoalex]

Hi. I see that text can be set to NextionText as char[] or int value only. What about float?

P.S. I did not find any solution for Nextion displays for this in C++. For this now I use this code.
void writeFloatToDisplay(NextionText target, double value) { char buffer[10]; dtostrf(value, 5, 2, buffer); target.setText(buffer); }

That seems the best option. If you wanted to wrap that in another function on INextionNumericalValued I'd happily accept a PR.
