+operations one would usually expect out of such a library and offers them both
+in non-modifying and modifying versions where applicable.  It also tries to be
+efficient where plausible.  Each quaternion is made up of @code{float}s, which
+by default are @code{single-float}s, as they do not require value boxing on
+most modern systems and compilers.")
