.NET Framework (current version)
Defines an explicit conversion of a single-precision floating-point number to a Decimal.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
-
Type:
System::Single
The single-precision floating-point number to convert.
| Exception | Condition |
|---|---|
| OverflowException | value is less than Decimal::MinValue or greater than Decimal::MaxValue. -or- value is Single::NaN, Single::PositiveInfinity, or Single::NegativeInfinity. |
The following example converts Single values to Decimal numbers by using the Single to Decimal conversion. This conversion requires the op_Explicit operator in Visual Basic.
// Example of the explicit conversion from float to Decimal. using namespace System; #define formatter "{0,16:E7}{1,33}" // 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 float argument; catch exceptions that are thrown. void DecimalFromSingle( float argument ) { Object^ decValue; // Convert the float argument to a Decimal value. try { decValue = (Decimal)argument; } catch ( Exception^ ex ) { decValue = GetExceptionType( ex ); } Console::WriteLine( formatter, argument, decValue ); } int main() { Console::WriteLine( "This example of the explicit conversion from float " "to Decimal \ngenerates the following output.\n" ); Console::WriteLine( formatter, "float argument", "Decimal value" ); Console::WriteLine( formatter, "--------------", "-------------" ); // Convert float values and display the results. DecimalFromSingle( 1.2345E-30F ); DecimalFromSingle( 1.2345E-26F ); DecimalFromSingle( 1.23456E-22F ); DecimalFromSingle( 1.23456E-12F ); DecimalFromSingle( 1.234567F ); DecimalFromSingle( 1.234567E+12F ); DecimalFromSingle( 1.2345678E+28F ); DecimalFromSingle( 1.2345678E+30F ); } /* This example of the explicit conversion from float to Decimal generates the following output. float argument Decimal value -------------- ------------- 1.2345000E-030 0 1.2345000E-026 0.0000000000000000000000000123 1.2345600E-022 0.000000000000000000000123456 1.2345600E-012 0.00000000000123456 1.2345671E+000 1.234567 1.2345670E+012 1234567000000 1.2345678E+028 12345680000000000000000000000 1.2345678E+030 OverflowException */
