f:float32 -> bool
Parameters
- f
- Type: System
. . :: . Single
A single-precision floating-point number.

Floating-point operations return PositiveInfinity to signal an overflow condition.
Examples
The following code example demonstrates the IsPositiveInfinity method.
' 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
// This will return true.
Console.WriteLine("IsPositiveInfinity(4.0F / 0) == {0}.", Single.IsPositiveInfinity(4.0F / 0) ? "true" : "false");
// This will return true.
Console::WriteLine( "IsPositiveInfinity(4.0F / 0) == {0}.", Single::IsPositiveInfinity( 4.0F / zero ) ? (String^)"true" : "false" );
