WebLooking in the IQmathLib.h include file the only functions which use floating point arugments are the _IQ n toF and _IQ n toD which convert an IQ number to single-precision or double-precision floating point values. Therefore, believe that only these two sets of functions are affected. [but haven't tested all the functions on a LM4F]
