That depends on your development environment. If e.g. using arm gcc and makefiles, you will have to change this in your projects makefile. I don't know exactly how projects in the latests SDK is structured, but this is what i had to to in a/some previous version(s) when i had the same issue as you.

I found the answer on the forum after posting here. Anyways you need to go to

Project options -->Select Common Configuration -->Code -->Prinf/Scanf now change it here to Float supported.

Try adding -u _printf_float in the linking flags.
