	c As Double
) As Double

public:
static double Discriminant(
	double a, 
	double b, 
	double c
)

static member Discriminant : 
        a : float * 
        b : float * 
        c : float -> float

Parameters

a: Type: SystemDouble
The coefficient of the 2nd order monomial.
b: Type: SystemDouble
The coefficient of the 1st order monomial.
c: Type: SystemDouble
The coefficient of the 0th order monomial.

Return Value

Type: Double
The value of the discriminant.

Remarks

Note that when computing RealRoots, a tolerance is used that may cause the number of roots to differ relative to what analysis of the discriminant would imply.
