Examples
The following code example illustrates the use of IsPositiveInfinity:
// 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
Remarks
Floating-point operations return PositiveInfinity to signal an overflow condition.
