ElementaryIsInfinite Method (Double)Extreme Optimization Numerical Libraries for .NET Professional
Returns whether the specified double-precision floating-point number equals positive or negative infinity.

Namespace: Extreme.Mathematics
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 6.0.16073.0 (6.0.16312.0)
Syntax
C#
VB
C++
F#
Copy
public static bool IsInfinite(
	double x
)
Public Shared Function IsInfinite ( 
	x As Double
) As Boolean
public:
static bool IsInfinite(
	double x
)
static member IsInfinite : 
        x : float -> bool

Parameters

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

Return Value

Type: Boolean
if x is not NaN and not infinite; otherwise .
Remarks

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