        !            25: .SH DESCRIPTION
        !            26: These functions compute the designated inverse hyperbolic functions for real
        !            27: arguments.
        !            28: .SH ERROR (due to Roundoff etc.)
        !            29: These functions inherit much of their error from log1p described in
        !            30: exp(3M).  On a VAX, acosh is accurate to about 3 \*(ups,
        !            31: asinh and atanh to about 2 \*(ups.
        !            32: An \*(up is one \fIU\fRnit in the \fIL\fRast \fIP\fRlace carried.
        !            33: .SH DIAGNOSTICS
        !            34: Acosh returns the reserved operand on a VAX if the argument is less than 1.
        !            35: .PP
        !            36: Atanh returns the reserved operand on a VAX if the argument has absolute
        !            37: value bigger than or equal to 1.
