ElementaryIsNaN Method (Double)Extreme Optimization Numerical Libraries for .NET Professional
Returns whether the specified double-precision floating-point number is a Not-A-Number (NaN) value.

Namespace: Extreme.Mathematics
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 6.0.16073.0 (6.0.16073.0)
Syntax
C#
VB
C++
F#
Copy
public static bool IsNaN(
	double x
)
Public Shared Function IsNaN ( 
	x As Double
) As Boolean
public:
static bool IsNaN(
	double x
)
static member IsNaN : 
        x : float -> bool

Parameters

x
Type: SystemDouble
A double-precision floating-point number.

Return Value

Type: Boolean
if x is a NaN; otherwise .
Remarks

This method is significantly faster than the IsNaN(Double) method in many situations.
