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

- These functions inherit much of their error from _l_o_g_1_p described in
- _e_x_p(3M).

- In the diagnostics below, functions in the standard math library _l_i_b_m._a,
- are referred to as -_l_m versions, those in math library _l_i_b_m_x._a are
- referred to as -_l_m_x versions, and those in the the BSD math library
- _l_i_b_m_4_3._a are referred to as -_l_m_4_3 versions. The -_l_m and -_l_m_x versions
- always return the default Quiet NaN and set _e_r_r_n_o to EDOM when a NaN is
- used as an argument. A NaN argument usually causes the -_l_m_4_3 versions to
- return the same argument. The -_l_m_4_3 versions never set _e_r_r_n_o.
-
- _a_c_o_s_h returns the default quiet NaN if the argument is less than 1. The
- -_l_m and -_l_m_x versions also set _e_r_r_n_o to EDOM.
-
- _a_t_a_n_h returns the default quiet NaN if the argument has absolute value
- greater than 1. The -_l_m and -_l_m_x versions also set _e_r_r_n_o to EDOM.
-
- See matherr(3M) for a description of error handling for -_l_m_x functions.
