/* Naming convention: generic macros are defining using
   __TGMATH_CPLX*, __TGMATH_REAL*, and __TGMATH_CPLX_ONLY.  _CPLX
   means the generic argument(s) may be real or complex, _REAL means
   real only, _CPLX means complex only.  If there is no suffix, we are
   defining a function of one argument.  If the suffix is _n
   it is a function of n arguments.  We only define these macros for
   values of n that are needed. */
