(追記ここまで)(追記) (追記ここまで)

Standard

Fortran 2008 and later

Class

Elemental function

Syntax

(削除)
result = erfc(x)
(削除ここまで)(追記)

result = erfc(x)

(追記ここまで)

Arguments

x - The type shall be real.

Return value

The return value is of type real and of the same kind as x. It lies in the range 0 \\leq(削除) erfc (削除ここまで)(追記) \\mathop{erfc}(x) (追記ここまで)(削除) (x) (削除ここまで) \\leq 2.

Example
