Is there a ready and working solution for converting from float to char?

Question

Arduino

Is there a ready and, most importantly, working solution for converting from float to char?
The examples on arduino.cc don't work.
PS The TFT library only understands char. I receive the data in float.

Answer 1

Did char() disappear somewhere? The main thing is that the passed value should be 0 <= x <= 255
upd: and of course it should be integer.

Answer 2

I don't quite understand the question, and I'm not an arduino programmer, but float is a floating point type and char is an integer, how are you going to "translate" float to char? If you need to discard the fractional part, maybe the round, floor or ceil functions will help you?
