Public Shared Function IsNegativeInfinity (f As Single) As Boolean

Parameters

f
Single

A single-precision floating-point number.

Examples

The following code example demonstrates the IsNegativeInfinity method.

// This will return true.
Console.WriteLine("IsNegativeInfinity(-5.0F / 0) == {0}.", Single.IsNegativeInfinity(-5.0F / 0) ? "true" : "false");

// This will return true.
printfn $"IsNegativeInfinity(-5.0F / 0) == {Single.IsNegativeInfinity(-5f / 0f)}."

' This will return True.
Console.Write("IsNegativeInfinity(-5.0 / 0) = ")
If Single.IsNegativeInfinity(-5 / 0) Then
 Console.WriteLine("True.")
Else
 Console.WriteLine("False.")
End If

Remarks

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