std::float_round_style(3)

NAME
std::float_round_style - std::float_round_style

Synopsis
   Defined in header <limits>
   enum float_round_style {
       round_indeterminate = -1,
       round_toward_zero = 0,
       round_to_nearest = 1,
       round_toward_infinity = 2,
       round_toward_neg_infinity = 3
   };
   Enumeration constants of type std::float_round_style indicate the rounding style
   used by floating-point arithmetic whenever a result of an expression is stored in an
   object of a floating-point type. The values are:
