-     These functions compute the designated inverse hyperbolic
-     functions for real arguments.

-     These functions inherit much of their error from log1p
-     described in exp(3M).  On a VAX, acosh is accurate to about
-     3 _\bu_\bl_\bps, asinh and atanh to about 2 _\bu_\bl_\bps.  An _\bu_\bl_\bp is one _\bUnit
-     in the _\bLast _\bPlace carried.
+     The a\bac\bco\bos\bsh\bh() function computes the inverse hyperbolic cosine of the real
+     argument _\bx. For a discussion of error due to roundoff, see math(3).

-     Acosh returns the reserved operand on a VAX if the argument
-     is less than 1.
-
-     Atanh returns the reserved operand on a VAX if the argument
-     has absolute value bigger than or equal to 1.

+     The a\bac\bco\bos\bsh\bh() function returns the inverse hyperbolic cosine of _\bx. On the
+     VAX and Tahoe, if the argument is less than one a\bac\bco\bos\bsh\bh() sets the global
+     variable _\be_\br_\br_\bn_\bo to EDOM and causes a reserved operand fault.
