/* __GLIBC_FLT_EVAL_METHOD is the value of FLT_EVAL_METHOD used to
   determine the evaluation method typedefs such as float_t and
   double_t.  It must be a value from C11 or TS 18661-3:2015, and not
   -1.  */

/* In the default version of this header, follow __FLT_EVAL_METHOD__.
   -1 is mapped to 2 (considering evaluation as long double to be a
   conservatively safe assumption), and if __FLT_EVAL_METHOD__ is not
   defined then assume there is no excess precision and use the value
   0.  */
