In my code I use the half precision floating point (__fp16). I have set the compiler flag -mfp16-format=ieee, but when linking I get the error: "undefined reference to `__aeabi_f2h'." I probably only need to set a linker flag, but I don't know which one and I haven't found the solution yet. So if anyone could point me in the right direction it would be much appreciated.</SPAN></BODY></HTML> Thu, 16 Jun 2016 00:18:34 GMT https://community.nxp.com/t5/LPCXpresso-IDE/fp16-Halfprecision-floating-point-problem/m-p/529378#M1460 lpcware 2016-06-16T00:18:34Z Re: __fp16 (Halfprecision floating point) problem https://community.nxp.com/t5/LPCXpresso-IDE/fp16-Halfprecision-floating-point-problem/m-p/529379#M1461 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by CodeRedSupport on Tue May 15 09:49:55 MST 2012</STRONG><BR /><SPAN>Hi,</SPAN><BR /><BR /><SPAN>The issue is that half precision floating point is not supported in Redlib.
