I believe you can't. Even though you can specify that a real-time
module/task/thread can use the math coprocessor (I'm assuming your in an x86
architecture), the kernel versions of printf don't support floating point
conversions.
I think that the best you can do is to send the data to a user-task via a
real-time FIFO (or dump the data into shared memory) for printing.
