36 .\"O The (unimplemented) function
38 .\"O is the complex version of the error function.
39 .\"O erf(z) = 2/sqrt(pi) * integral from 0 to z of exp(\-t*t) dt.
44 erf(z) = 2/sqrt(pi) * exp(\-t*t) dt の 0 から z までの積分
49 .\"O is defined as cerfc(z) = 1\-cerf(z).
51 関数の定義は cerfc(z) = 1-cerf(z) である。
52 .\"O .\" must check 1/sqrt(2*pi) ?
53 .\" 1/sqrt(2*pi) のチェックをしなくてもいいの?
54 .\"O .SH "CONFORMING TO"
56 .\"O The function names are reserved for future use in C99.
57 関数名は C99 で今後使用するために予約されている。
60 .\"O Not yet in glibc, as at version 2.12.
61 .\"O .\" But reserved in NAMESPACE.
62 バージョン 2.12 時点では、glibc にはまだ実装されていない。
