I have already  checked it. but I can't sure that it is safe or not.
" IQmathLib.h" include things below.
I think that It need to be verified totally.

extern    int  _IQ1toa(char *A, const char *B, long C);
#define   _IQtoQ1(A)     (int) ((A) * 2.0)

 but I can't sure that it is safe or not.

Its safe... :)

  I tested the IQmath in CLA Task, but it didn't works
  Because CLA does not support calling functions with more than two arguments.
  I think that it's very difficult to use IQmath in CLA Task.

I read it but, I can't find out explanation about IQmath in CLA task function.
that is just the ways for using FIR filter, one is to use CLA floating FIR filter, another is to use IQmath and floating point FIR filter.
There is not any relation between CLA and IQmath.
Now, I'm trying to convert my program into floating point program.
I think that CLA function is not perfect yet.
