설명

이 생성자는 반올림 value 을 사용하여 15개의 유효 자릿수로 반올림합니다. 이 작업은 숫자가 15자리를 초과하고 덜 중요한 숫자가 0인 경우에도 수행됩니다.

적용 대상

Decimal(Int32)

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Decimal의 새 인스턴스를 지정된 32비트 부호 있는 정수 값으로 초기화합니다.

public:
 Decimal(int value);

public Decimal (int value);

new decimal : int -> decimal

Public Sub New (value As Integer)

매개 변수

value: Int32

Decimal로 나타낼 값입니다.

적용 대상

Decimal(Int32[])

Source:: Decimal.cs

Source:: Decimal.cs

Source:: Decimal.cs

Decimal의 새 인스턴스를 이진으로 표현되며 지정한 배열에 포함된 10진 값으로 초기화합니다.

public:
 Decimal(cli::array <int> ^ bits);

public Decimal (int[] bits);

new decimal : int[] -> decimal

Public Sub New (bits As Integer())

매개 변수

bits: Int32[]

10진 값 표현을 포함하는 32비트 부호 있는 정수 배열입니다.

예외

ArgumentNullException

bits이(가) null인 경우

ArgumentException

bits의 길이가 4가 아닙니다.

또는

bits의 10진수 값 표현이 올바르지 않습니다.

예제

다음 코드 예제에서는 4 Int32 개의 값 배열로 구조를 초기화하는 생성자 오버로드를 Decimal 사용하여 여러 Decimal 숫자를 만듭니다.

설명

숫자의 Decimal 이진 표현은 1비트 부호, 96비트 정수 및 정수 수를 나누고 소수 자릿수 부분을 지정하는 데 사용되는 배율 인수로 구성됩니다. 배율 인수는 암시적으로 숫자 10이며 0에서 28 사이의 지수로 증가합니다.

bits 는 32비트 부명의 정수로 구성된 4개 요소의 긴 배열입니다.

bits [0], bits [1], bits [2]에는 96비트 정수의 낮음, 중간 및 상위 32비트가 포함됩니다.

bits [3]은 배율 인수 및 기호를 포함하며 다음 부분으로 구성됩니다.

하위 단어인 비트 0~15는 사용되지 않으며 0이어야 합니다.

비트 16~23은 0에서 28 사이의 지수를 포함해야 하며, 이는 정수 수를 나누려면 10의 힘을 나타냅니다.

비트 24~30은 사용되지 않으며 0이어야 합니다.

비트 31에는 기호가 포함됩니다. 0은 긍정을 의미하고 1은 음수입니다.

숫자 값에는 몇 가지 가능한 이진 표현이 있을 수 있습니다. 모두 동일하게 유효하고 숫자로 동일합니다. 비트 표현은 음수와 양수 0을 구분합니다. 이러한 값은 모든 작업에서 같음으로 처리됩니다.
