This is actually a C language question, rather than an Eclipse question.

The compiler does not analyze the format string in your printf() function call. Thus, it cannot know that you want the second argument to be float/double, as it is not defined so in the printf() function prototype. Please note that this applies to all variable argument lists, using <stdarg.h> or <varargs.h>.
