Decimal.ToInt64 메서드
지정된 Decimal의 값을 64비트 부호 있는 정수로 변환합니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Shared Function ToInt64 ( _
d As Decimal _
) As Long
‘사용 방법
Dim d As Decimal
Dim returnValue As Long
returnValue = Decimal.ToInt64(d)
public static long ToInt64 (
decimal d
)
public:
static long long ToInt64 (
Decimal d
)
public static long ToInt64 (
Decimal d
)
public static function ToInt64 (
d : decimal
) : long
매개 변수
- d
변환할 Decimal 값입니다.
반환 값
d의 값에 해당하는 64비트의 부호 있는 정수입니다.
예외
| 예외 형식 | 조건 |
|---|---|
d가 Int64.MinValue보다 작거나 Int64.MaxValue보다 큰 경우 |
설명
반환 값은 10진 값의 정수 부분입니다. 소수 자리는 잘립니다.
예제
다음 코드 예제에서는 ToInt64 메서드를 사용하여 Decimal 숫자를 Int64 값으로 변환합니다.
