- These functions compute the designated inverse hyperbolic functions
- for real arguments.
-
- Roundoff errors are derived from lloogg11pp, described in eexxpp(3M).
-
- Functions in the standard math library (lliibbmm..aa) are referred to as --llmm
- versions. Those in mathx library (lliibbmmxx..aa) are referred to as --llmmxx
- versions, and those in the the BSD math library (lliibbmm4433..aa) are
- referred to as --llmm4433 versions.

- The --llmm and --llmmxx versions always return the default Quiet NaN and set
- eerrrrnnoo to EDOM when a NaN is used as an argument. A NaN argument
- usually causes the --llmm4433 versions to return the same argument. The
- --llmm4433 versions never set eerrrrnnoo.
-
- aaccoosshh returns the default quiet NaN if the argument is less than 1.
- The --llmm and --llmmxx versions also set eerrrrnnoo to EDOM.
-
- aattaannhh returns the default quiet NaN if the argument has an absolute
- value greater than 1. The --llmm and --llmmxx versions also set eerrrrnnoo to
- EDOM.
-
- See mmaatthheerrrr(3M) for a description of error handling for --llmmxx
- functions.
