``````public ref class Temperature
{
public:
static property double MinValue
{
double get()
{
return Double::MinValue;
}
}

static property double MaxValue
{
double get()
{

double m_value;

public:
property double Value
{
double get()
{
return m_value;
}
void set( double value )
{
m_value = value;
}
}

property double Celsius
{
double get()
{
return (m_value - 32.0) / 1.8;
}
void set( double value )
{
m_value = 1.8 * value + 32.0;
}
}
};

## Hinweise

Der Wert dieser Konstante ist positiv 1.7976931348623157 e + 308.The value of this constant is positive 1.7976931348623157E+308.

Das Ergebnis eines Vorgangs, der überschreitet, Double.MaxValue ist Double.PositiveInfinity .The result of an operation that exceeds Double.MaxValue is Double.PositiveInfinity. Im folgenden Beispiel werden Double.PositiveInfinity Ergebnisse aus Additions-, Multiplikations-und exponentiations Vorgängen ausgegeben, wenn das Ergebnis überschreitet Double.MaxValue .In the following example, Double.PositiveInfinity results from addition, multiplication, and exponentiation operations when the result exceeds Double.MaxValue.
