You hjave tp provided these functions or use a framework that provides these function.

Some of the GNU/GCC​ chains provide a function reduced library which doesn't support floats. Review project settings for a check box item referring to printf or floats.

there is a switch when you start a project,

select:

NewLib-Nano with floating point support in printf

not NewLibNano with floating point support in Printf and Scanf0690X000008wPa6QAE.jpg
