87 \fBasinh\fP() 関数は \fIx\fP 逆双曲線正弦(inverse hyperbolic sine)を
88 計算する。すなわち、その双曲線正弦(hyperbolic sine)が \fIx\fP に なるような値である。
90 成功すると、これらの関数は \fIx\fP の逆双曲線正弦を返す。
92 \fIx\fP が NaN の場合、NaN が返される。
94 \fIx\fP が +0 (\-0) の場合、+0 (\-0) が返される。
97 .\" POSIX.1-2001 documents an optional range error for subnormal x;
98 .\" glibc 2.8 does not do this.
99 \fIx\fP が正の無限大 (負の無限大) の場合、正の無限大 (負の無限大) が返される。
