Public Shared Function Log1PlusX ( 
	x As Quad
) As Quad

public:
static Quad Log1PlusX(
	Quad x
)

static member Log1PlusX : 
        x : Quad -> Quad 

Parameters

x

Type: Extreme.MathematicsQuad
A real number greater than -1.

Return Value

For small values of x, the logarithm of 1 + x is close to zero. When the logarithm is evaluated directly, this can cause significant round-off error. This function resolves this problem by using a direct approximations for x close to 1.
