Hello all , i use stm32f103c6 with IAR IDE in my project . To an already existing stable code(which does not have float variables) . I have added a piece of code(which has some float variables) and when i built the project , i am facing the below linker errors . Seems like these are Libraries for Floating point operations . Why am i getting these errors ? Does STM32F103C6 support float point operations ?
