ERFC_SCALED

Elemental Intrinsic Function (Generic): Returns the scaled complementary error function of an argument.

result = ERFC_SCALED (x)

x

(Input) Must be of type real.

Results

The result type and kind are the same as x.

The result has a value equal to a processor-dependent approximation to the exponentially-scaled complementary error function of

NOTE:

The complementary error function is asymptotic to note graphic a. As such it underflows for note graphicb when using IEEE single precision arithmetic. The exponentially-scaled complementary error function is asymptotic to note graphic c. As such it does not underflow until note graphic d.

Example

ERFC_SCALED (20.0) has the approximate value 0.02817434874.
