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