/* __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. */
