Umm, just like printk, rtl_printf doesn't support floats. Rationale:
floats don't (normally) belong in the kernel. However, as we all know,
for scientific or other applications using rt-linux, that design choice
doesn't help us much... :( I myself have half a mind to patch rtl_printf
myself so that I can printf some floats. It shouldn't be too tough.. :/
