Elementary.IsNaN Method

Definition

Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.0

IsNaN(Double)	Returns whether the specified double-precision floating-point number is a Not-A-Number (NaN) value.
IsNaN(Single)	Returns whether the specified float-precision floating-point number is a Not-A-Number (NaN) value.

Returns whether the specified double-precision floating-point number is a Not-A-Number (NaN) value.

public static bool IsNaN(
	double x
)

Visual Basic

Public Shared Function IsNaN ( 
	x As Double
) As Boolean

C++/CLI

public:
static bool IsNaN(
	double x
)

static member IsNaN : 
        x : float -> bool

Boolean
true if x is a NaN; otherwise false.

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

Returns whether the specified float-precision floating-point number is a Not-A-Number (NaN) value.

public static bool IsNaN(
	float x
)

Visual Basic

Public Shared Function IsNaN ( 
	x As Single
) As Boolean

C++/CLI

public:
static bool IsNaN(
	float x
)

static member IsNaN : 
        x : float32 -> bool

Boolean
true if x is a NaN; otherwise false.

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