public static function IsNegativeInfinity (
	f : float
) : boolean

Parameters

f

A single-precision floating-point number.

Return Value

true if f evaluates to NegativeInfinity; otherwise, false.

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

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.
Console.WriteLine("IsNegativeInfinity(-5.0F / 0) == {0}.", 
    (Single.IsNegativeInfinity((-5 / zero))) ? "true" : "false");
