Single.IsPositiveInfinity(Single) Method

Definition

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

``````public:
static bool IsPositiveInfinity(float f);``````
``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

`true` if `f` evaluates to PositiveInfinity; otherwise, `false`.

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.
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.
