Single.IsPositiveInfinity Method

.NET Framework 1.1

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

```[Visual Basic]
Public Shared Function IsPositiveInfinity( _
ByVal f As Single _
) As Boolean
[C#]
public static bool IsPositiveInfinity(
float f
);
[C++]
public: static bool IsPositiveInfinity(
float f
);
[JScript]
public static function IsPositiveInfinity(
f : float
) : Boolean;```

Parameters

f
A single-precision floating point number.

Return Value

true if f evaluates to PositiveInfinity; otherwise, false.

Remarks

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

Example

[Visual Basic, C#, C++] The following sample demonstrates the IsPositiveInfinity method.

```[Visual Basic]
' 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

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

[C++]
// This will return true.
Console::WriteLine(S"IsPositiveInfinity(4.0F / 0) == {0}.", Single::IsPositiveInfinity(4.0F / zero) ? S"true" : S"false");
```
