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
The complementary error function is asymptotic to . As such it underflows for when using IEEE single precision arithmetic. The exponentially-scaled complementary error function is asymptotic to . As such it does not underflow until .
Example
ERFC_SCALED (20.0) has the approximate value 0.02817434874.
