	double x
)
static member IntegralCi : 
        x : float -> float

Parameters

x
Double
The argument, which must be non-negative.

Return Value

The value of Ci(x).

Remarks

The cosine integral is defined as:

The cosine integral diverges logrithmically to negative inifity at the origin and executes a damped oscilation arround zero as its argument increases.

Exceptions
