This is specified in the Features list at the start of the LPC43xx user manual - but you are correct that the manual only lists the non-floating point instructions. I'll flag this to our docs team.</SPAN><BR /><BR /><SPAN><SPAN>For more information on using floating point on LPC43xx see </SPAN><A class="jive-link-external-small" href="https://community.nxp.com/external-link.jspa?url=http%3A%2F%2Fwww.lpcware.com%2Fcontent%2Ffaq%2Flpcxpresso%2Fcm4-floating-point" rel="nofollow" target="_blank">http://www.lpcware.com/content/faq/lpcxpresso/cm4-floating-point</A><SPAN> (which gives some general info as well as LPCXpresso specifics), and if using another toolchain, check their documentation.</SPAN></SPAN><BR /><BR /><SPAN>Regards,</SPAN><BR /><SPAN>LPCXpresso Support.</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:55:04 GMT https://community.nxp.com/t5/LPC-Microcontrollers/FPU-Instruction-Set/m-p/569887#M18030 lpcware 2016-06-15T18:55:04Z
