[C#/COMMON/.NET6] Math 클래스 : Round 정적 메소드에서 Normal Rounding 사용하기

■ Math 클래스의 Round 정적 메소드에서 Normal Rounding을 사용하는 방법을 보여준다.

▶ 예제 코드 (C#)


//                         Banker's Rounding (Default)   Normal Rounding
Console.WriteLine($"0.5 : {Math.Round(0.5, 0)         } {Math.Round(0.5, 0, MidpointRounding.AwayFromZero)}");
Console.WriteLine($"1.5 : {Math.Round(1.5, 0)         } {Math.Round(1.5, 0, MidpointRounding.AwayFromZero)}");
Console.WriteLine($"2.5 : {Math.Round(2.5, 0)         } {Math.Round(2.5, 0, MidpointRounding.AwayFromZero)}");
Console.WriteLine($"3.5 : {Math.Round(3.5, 0)         } {Math.Round(3.5, 0, MidpointRounding.AwayFromZero)}");
Console.WriteLine($"4.5 : {Math.Round(4.5, 0)         } {Math.Round(4.5, 0, MidpointRounding.AwayFromZero)}");
Console.WriteLine($"5.5 : {Math.Round(5.5, 0)         } {Math.Round(5.5, 0, MidpointRounding.AwayFromZero)}");

/*
0.5 : 0 1

2.5 : 2 3
3.5 : 4 4

Console.WriteLine($"0.5 : {Math.Round(0.5, 0) } {Math.Round(0.5, 0, MidpointRounding.AwayFromZero)}");

0.5 : 0 1

1.5 : 2 2

2.5 : 2 3

3.5 : 4 4

4.5 : 4 5

5.5 : 6 6
