# Double.MinValue Pole

## Definice

Představuje nejmenší možnou Doublehodnotu . Toto pole je konstantní.

``public: double MinValue = -1.7976931348623157E+308;``
``public const double MinValue = -1.7976931348623157E+308;``
``val mutable MinValue : double``
``Public Const MinValue As Double  = -1.7976931348623157E+308``

#### Hodnota pole

Double

Následující příklad kódu znázorňuje použití Double.MinValue:

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

static property double MaxValue
{
double get()
{
return Double::MaxValue;
}
}

protected:
// The value holder
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;
}
}
};
``````
``````public class Temperature {
public static double MinValue {
get {
return Double.MinValue;
}
}

public static double MaxValue {
get {

}
}

// The value holder
protected double m_value;

public double Value {
get {
return m_value;
}
set {
m_value = value;
}
}

public double Celsius {
get {
return (m_value-32.0)/1.8;
}
set {
m_value = 1.8*value+32.0;
}
}
}
``````
``````type Temperature() =

static member MaxValue =

with get () =

and set (value) =

``````Public Class Temperature

## Poznámky

Hodnota této konstanty je záporná 1,7976931348623157E+308.

Výsledek operace, která je menší než Double.MinValue je Double.NegativeInfinity. V následujícím příkladu Double.NegativeInfinity je výsledkem operací odčítání a násobení, pokud je výsledek menší než Double.MinValue.

``````using System;

public class Example
{
public static void Main()
{
double result1 = -7.997e307 + -9.985e307;
Console.WriteLine("{0} (Negative Infinity: {1})",
result1, Double.IsNegativeInfinity(result1));

double result2 = -1.5935e250 * 7.948e110;
Console.WriteLine("{0} (Negative Infinity: {1})",
result2, Double.IsNegativeInfinity(result2));
}

// The example displays the following output:
//    -Infinity (Negative Infinity: True)
