Decimal Explicit Conversion (Decimal to SByte)
Converts a Decimal to an 8-bit signed integer.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Decimal
The value to convert.
| Exception | Condition |
|---|---|
| OverflowException | value is less than SByte::MinValue or greater than SByte::MaxValue. |
This operator supports the explicit conversion of a Decimal to a SByte. The syntax for such explicit conversions is language-dependent, and individual language compilers can provide different implementations and return different results. The example illustrates the different return values when you explicitly convert a Decimal value to a Byte and an SByte value by using C# and Visual Basic. To perform a conversion that is independent of language, you can call the ToSByte method or the Convert::ToSByte(Decimal) method.
The following code example converts Decimal numbers to SByte values using the explicit Decimal to SByte conversion.
// Example of the explicit conversions from Decimal to char and // Decimal to unsigned char. using namespace System; #define formatter "{0,16}{1,19}{2,19}" // Get the exception type name; remove the namespace prefix. String^ GetExceptionType( Exception^ ex ) { String^ exceptionType = ex->GetType()->ToString(); return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 ); } // Convert the Decimal argument; catch exceptions that are thrown. void DecimalToS_Byte( Decimal argument ) { Object^ ByteValue; Object^ SByteValue; // Convert the argument to an unsigned byte value. try { ByteValue = (unsigned char)argument; } catch ( Exception^ ex ) { ByteValue = GetExceptionType( ex ); } // Convert the argument to a signed byte value. // The cast (char) causes a compile error. try { SByteValue = (signed char)argument; } catch ( Exception^ ex ) { SByteValue = GetExceptionType( ex ); } Console::WriteLine( formatter, argument, ByteValue, SByteValue ); } int main() { Console::WriteLine( "This example of the explicit conversions from Decimal " "to signed \nand unsigned 8-bit char generates the " "following output.
