Floating point support in ARM926ejs

[Amarnath MB]

joel,

Inside the tests, I''m not getting an integer only printf(). It simply
prints format specifier as such i.e. %f.
Yes, Sebastian is right, Thanks for the help, is it anywhere documented
that samples will be using a different set of
implementation for stdio or any other standard library calls? Since I'm new
to RTEMS I assumed that samples will
behave exactly the same as my application.

*Thank you & Regards,*
*Amarnath MB*
