[BUG FOUND] Printf/Sprintf for float point variables not working.

I found a quote that this problem had been fixed in an earlier version, but the problem is reoccurring. Using STM32CubeIDE Version. 1.2.1 Build: 5190_20200115_1224 (UTC)

This problem is fixed in STM32CubeIDE ver.1.0.2.

Still need to add the flag:

Workaround in older version is to add "-u _printf_float" to MCU GCC Linker -> Miscellaneous -> Other flags.
