From 7.22:
       [#6] For each unsuffixed function in <complex.h> that is not
       a c-prefixed counterpart to  a  function  in  <math.h>,  the
       corresponding  type-generic  macro  has the same name as the
       function.  These type-generic macros are:

            carg          conj          creal
            cimag         cproj

       Use of the macro with any real or complex argument invokes a
       complex function.

The problem is that carg(real float variable) will call the long
double function.
