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

構文

result = ERFC (x)

x

(Input) Must be of type real.

Results

The result type and kind is the same as x. The result is in the range 0 to 2.

ERFC returns 1 - ERF(x) and is defined as follows:

ERFC returns 1 - ERF(x)

ERFC is provided because of the extreme loss of relative accuracy if ERF(x) is called for large x and the result is subtracted from 1.
