Returns a value indicating whether the specified number evaluates to positive infinity.
public:
static bool IsPositiveInfinity(double d);
public:
static bool IsPositiveInfinity(double d) = System::Numerics::INumberBase<double>::IsPositiveInfinity;
public static bool IsPositiveInfinity(double d);
static member IsPositiveInfinity : double -> bool
Public Shared Function IsPositiveInfinity (d As Double) As Boolean
- d
- Double
A double-precision floating-point number.
true
if d
evaluates to PositiveInfinity; otherwise, false
.
The following code example illustrates the use of IsPositiveInfinity:
// This will return S"true".
Console::WriteLine( "IsPositiveInfinity(4.0 / 0) == {0}.", Double::IsPositiveInfinity( 4.0 / zero ) ? (String^)"true" : "false" );
// This will return "true".
Console.WriteLine("IsPositiveInfinity(4.0 / 0) == {0}.", Double.IsPositiveInfinity(4.0 / 0) ? "true" : "false");
// This will return "true".
printfn $"IsPositiveInfinity(4.0 / 0) = %b{Double.IsPositiveInfinity(4. / 0.)}."
' This will return "True".
Console.Write("IsPositiveInfinity(4.0 / 0) = ")
If Double.IsPositiveInfinity(4 / 0) Then
Console.WriteLine("True.")
Else
Console.WriteLine("False.")
End If
Floating-point operations return PositiveInfinity to signal an overflow condition.
