  19.      These routines are not available for programs compiled with the O32 ABI.
  20.  
  21.      Functions in the standard math library (_llll_iiii_bbbb_mmmm_...._aaaa) are referred to as _----_llll_mmmm
  22.      versions. Those in mathx library (_llll_iiii_bbbb_mmmm_xxxx_...._aaaa) are referred to as _----_llll_mmmm_xxxx
  23.      versions, and those in the the BSD math library (_llll_iiii_bbbb_mmmm_4444_3333_...._aaaa) are referred
  24.      to as _----_llll_mmmm_4444_3333 versions.
  25.  
  26.      The _nnnn_aaaa_nnnn functions return a quiet NaN, if available, with content
  27.      indicated through _t_a_g_p. If the implementation does not support quiet
  28.      NaNs, the functions return zero.

  31.      The _----_llll_mmmm and _----_llll_mmmm_xxxx versions always return the default Quiet NaN and set
  32.      _eeee_rrrr_rrrr_nnnn_oooo to EDOM when a NaN is used as an argument.  A NaN argument usually
  33.      causes the _----_llll_mmmm_4444_3333 versions to return the same argument.  The _----_llll_mmmm_4444_3333
  34.      versions never set _eeee_rrrr_rrrr_nnnn_oooo.
  35.  
  36.      See _mmmm_aaaa_tttt_hhhh_eeee_rrrr_rrrr(3M) for a description of error handling for _----_llll_mmmm_xxxx functions.
