convert float to char

hey, I measure temperature with lm35. I want to send the temp from transmitter to receiver, but I have to convert the float value (the temp) to char. somebody know how can I do it? thank you, Roi

Did you mean "to string"?

Like this: Serial.print(1.23456) gives "1.23". Here: https://www.arduino.cc/en/Serial/Print.
