    Hey Sivanathi,

    I think your issue is that you are loading a float into _IQtoa.  Section 4.2.5 of the IQmath Lib User's guide defines the inputs for IQtoa.  

    Here is the function definition:  

    int _IQtoa(char *A,  const char *B,   _iq C)

    You should be able to feed qC straight into _IQtoa.  

    Also, you can check for what _IQtoa() returns.  If it's currently returning a 2, this means that an illegal format was used.  

    Thanks,

    JD
