Represents the largest possible value of a Double. This field is constant.

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

Field Value

Value = 1.7976931348623157E+308

Examples

The following code example illustrates the use of Double.MaxValue:

public class Temperature {
 public static double MinValue {
 get {
 return Double.MinValue;
 }
 }

 public static double MaxValue {
 get {
 return Double.MaxValue;
 }
 }

 // 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 MinValue =
 Double.MinValue

 static member MaxValue =
 Double.MaxValue

 member val Value = 0. with get, set

 member this.Celsius
 with get () =
 (this.Value - 32.) / 1.8
 and set (value) =
 this.Value <- 1.8 * value + 32.
Public Class Temperature

 Public Shared ReadOnly Property MinValue() As Double
 Get
 Return Double.MinValue
 End Get
 End Property

 Public Shared ReadOnly Property MaxValue() As Double
 Get
 Return Double.MaxValue
 End Get
 End Property

 ' The value holder
 Protected m_value As Double

 Public Property Value() As Double
 Get
 Return m_value
 End Get
 Set(ByVal Value As Double)
 m_value = Value
 End Set
 End Property

 Public Property Celsius() As Double
 Get
 Return (m_value - 32) / 1.8
 End Get
 Set(ByVal Value As Double)
 m_value = Value * 1.8 + 32
 End Set
 End Property
End Class

Remarks

The value of this constant is positive 1.7976931348623157E+308.

The result of an operation that exceeds Double.MaxValue is Double.PositiveInfinity. In the following example, Double.PositiveInfinity results from addition, multiplication, and exponentiation operations when the result exceeds Double.MaxValue.

using System;

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

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

 double result3 = Math.Pow(1.256e100, 1.34e20);
 Console.WriteLine("{0} (Positive Infinity: {1})",
 result3, Double.IsPositiveInfinity(result3));
 }
}
// The example displays the following output:
// Infinity (Positive Infinity: True)
// Infinity (Positive Infinity: True)
// Infinity (Positive Infinity: True)
open System

let result1 = 7.997e307 + 9.985e307
printfn $"{result1} (Positive Infinity: {Double.IsPositiveInfinity result1})"

let result2 = 1.5935e250 * 7.948e110
printfn $"{result2} (Positive Infinity: {Double.IsPositiveInfinity result2})"

let result3 = Math.Pow(1.256e100, 1.34e20)
printfn $"{result3} (Positive Infinity: {Double.IsPositiveInfinity result3})"
// The example displays the following output:
// Infinity (Positive Infinity: True)
// Infinity (Positive Infinity: True)
// Infinity (Positive Infinity: True)
Module Example
 Public Sub Main()
 Dim result1 As Double = 7.997e307 + 9.985e307
 Console.WriteLine("{0} (Positive Infinity: {1})", 
 result1, Double.IsPositiveInfinity(result1))
 
 Dim result2 As Double = 1.5935e250 * 7.948e110
 Console.WriteLine("{0} (Positive Infinity: {1})", 
 result2, Double.IsPositiveInfinity(result2))
 
 Dim result3 As Double = Math.Pow(1.256e100, 1.34e20)
 Console.WriteLine("{0} (Positive Infinity: {1})", 
 result3, Double.IsPositiveInfinity(result3))
 End Sub
End Module
' The example displays the following output:
' Infinity (Positive Infinity: True)
' Infinity (Positive Infinity: True)
' Infinity (Positive Infinity: True)
