Decimal.ToSingle 메서드
지정된 Decimal의 값을 값이 같은 단정밀도 부동 소수점 숫자로 변환합니다.
네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)
구문
‘선언
Public Shared Function ToSingle ( _
d As Decimal _
) As Single
‘사용 방법
Dim d As Decimal
Dim returnValue As Single
returnValue = Decimal.ToSingle(d)
public static float ToSingle (
decimal d
)
public:
static float ToSingle (
Decimal d
)
public static float ToSingle (
Decimal d
)
public static function ToSingle (
d : decimal
) : float
매개 변수
- d
변환할 Decimal 값입니다.
반환 값
d의 값에 해당하는 단정밀도 부동 소수점 숫자를 반환합니다.
설명
단정밀도 부동 소수점 숫자가 Decimal보다 적은 수의 유효 숫자를 가지므로 이 연산은 반올림 오류를 발생시킬 수 있습니다.
예제
다음 코드 예제에서는 ToSingle 메서드를 사용하여 Decimal 숫자를 Single 값으로 변환합니다.
