Empty string when using the sprinft() for float variables. #900

Hi. I got a problem while using the function sprintf(), when I was trying to output a float variable. The problem first appeared after using the dtostrf() function. If I add a float variable, I get an empty string as a result. Variables of type int are fine. As soon as the identifier "f" or "lf" appears in the arguments of the sprintf() function, after that sprintf() returns an empty string. I am using the Arduino_STM32-master library in the Arduino IDE 2.0.3. Board type STM32F4VE. Help me please. The third day, nothing happens.
