No. AFAIK, rtl_printf is (possibly indirectly) using the kernel's version
of snprintf(), which does not support FP.

Right, it doesn't matter, because there's no FP code in there to execute.
Either send the FP number off as is to user space through a FIFO, for a
user space application to print out, or write some "ftoa()"
implementation to use in your RTL thread, with rtl_printf("%s",
your_buffer).
