As of Model 204 7.5, SOUL has the following high-performance, high-precision versions of the IBM mathematical functions. These functions eliminate the need to use external math libraries though a site might choose to use an external library instead of these integrated $functions, anyway. In such a case, these $functions would result in calls to the external library.

Before Model 204 7.5, these $functions were available as part of the Sirius Mods.

See Notation conventions for methods for information about the conventions followed in the method descriptions.
