Returns a value indicating whether the specified number evaluates to positive infinity.

public:
 static bool IsPositiveInfinity(float f);
public:
 static bool IsPositiveInfinity(float f) = System::Numerics::INumberBase<float>::IsPositiveInfinity;
public static bool IsPositiveInfinity (float f);
static member IsPositiveInfinity : single -> bool
Public Shared Function IsPositiveInfinity (f As Single) As Boolean

Parameters

f
Single

A single-precision floating-point number.

Returns

Boolean

true if f evaluates to PositiveInfinity; otherwise, false.

Implements

IsPositiveInfinity(TSelf)

Examples

The following code example demonstrates the IsPositiveInfinity method.

// This will return true.
Console::WriteLine( "IsPositiveInfinity(4.0F / 0) == {0}.", Single::IsPositiveInfinity( 4.0F / zero ) ? (String^)"true" : "false" );

// This will return true.
Console.WriteLine("IsPositiveInfinity(4.0F / 0) == {0}.", Single.IsPositiveInfinity(4.0F / 0) ? "true" : "false");

// This will return true.
printfn $"IsPositiveInfinity(4.0F / 0) == {Single.IsPositiveInfinity(4f / 0f)}."

' This will return True.
Console.Write("IsPositiveInfinity(4.0 / 0) = ")
If Single.IsPositiveInfinity(4 / 0) Then
    Console.WriteLine("True.")
Else
    Console.WriteLine("False.")
End If

Remarks

Floating-point operations return PositiveInfinity to signal an overflow condition.
