Elementary..::..IsFinite Method

Elementary Class See Also 
Returns whether the specified double-precision floating-point number is finite.

Namespace: Extreme.Mathematics
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 4.2.11333.0 (4.2.12253.0)

Syntax

C# 
                      public static bool IsFinite(
	double x
)
Visual Basic (Declaration) 
                      Public Shared Function IsFinite ( _
	x As Double _
) As Boolean
Visual C++ 
                      public:
static bool IsFinite(
	double x
)
F# 
                      static member IsFinite : 
        x:float -> bool

Parameters

x
Type: System..::..Double
A double-precision floating-point number.

Return Value

true True true true (True in Visual Basic) if x is not NaN and not infinite; otherwise falseFalsefalsefalse (False in Visual Basic).

Remarks

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