Double.MaxValue Field
.NET Framework (current version)
Represents the largest possible value of a Double. This field is constant.
Assembly: mscorlib (in mscorlib.dll)
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.
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)
The following code example illustrates the use of MaxValue:
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
