ERFC_SCALED

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

Syntax

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 iconNote

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.
