It is a Cortex-M4, not Cortex-M4F, so AFAIK it doesn't have floating point hardware of STM32F3/4</p> <p><a href="http://uk.farnell.com/atmel/atsam4s-xpld/eval-sam4s16-xplained-kit/dp/2215343?ICID=I-ATM-1000082-HPBLOF-0125&amp;Ntt=2215343" rel="nofollow">http://uk.farnell.com/atmel/atsam4s-xpld/eval-sam4s16-xplained-kit/dp/2215343?ICID=I-ATM-1000082-HPBLOF-0125&amp;Ntt=2215343</a> </p>
