How can I use the "float_round_style" enum in C++

[Garett]

Hi, I had learned the C++ language in the IT subject of the First Year Of Junior college of the Commerce. I also had the knowledge of the Enumeration in C++ language. I can not know about the float_round_style enum in the C++ language. So, I want to know about the float_round_style enum in C++ language. If anyone has the knowledge of the float_round_style enum then reply me.

According to my knowledge about the float_round_style is that, The float_round_style can be used to defined the Enumerated type for floating types with possible rounding styles. The float_round_style can be the member of the round_style in the numeric_class class template. I hope you should understand. If you can not understand then reply me.

The float_round_style can be defined in the following manner in the C++ language :

enum float_round_style 
{
  round_indeterminate       = -1,
  round_to_nearest          = 1,
  round_toward_zero         = 0,
  round_toward_neg_infinity = 3
  round_toward_infinity     = 2,
};

The float_round_style can be declared as the static const float_round_style. The float_round_style can be used for the rounding style for the type. The float_round_style can be use for the specialization values. The Specializations of the float_round_style for integer types can returns the round_toward_zero. The float_round_style can be useful for all the types of floating point.

The several methods that can an implementation can be choose for rounding values of the floating-point into a value an integer, can be described by the Enumeration. The enumeration can describes the following :

1. round_toward_neg_infinity — round to more negative integer
2. round_toward_zero — round toward zero
3. round_indeterminate — rounding method cannot be determined
4. round_toward_infinity — round away from zero
5. round_to_nearest — round to nearest integer

    round_toward_beg_infinity	= 3
    round_toward_infinity	= 2,
    round_to_nearest		= 1,
    };
