The Decimal value returned by this method contains a maximum of 15 significant digits. If the value parameter contains more than 15 significant digits, it is rounded using rounding to nearest. The following example illustrates how the Convert::ToDecimal(Double) method uses rounding to nearest to return a Decimal value with 15 significant digits.
The following example converts a Double value to a Decimal value.
public: void ConvertDoubleDecimal( double doubleVal ) { Decimal decimalVal; // Conversion from double to decimal cannot overflow. decimalVal = System::Convert::ToDecimal( doubleVal ); System::Console::WriteLine( " {0} as a decimal is: {1}", doubleVal, decimalVal ); // Decimal to double conversion can overflow. try { doubleVal = System::Convert::ToDouble( decimalVal ); System::Console::WriteLine( " {0} as a double is: {1}", decimalVal, doubleVal ); } catch ( System::OverflowException^ ) { System::Console::WriteLine( "Overflow in decimal-to-double conversion." ); } }
