For information on quaternions, see the Wikipedia page.
This library supports standard operations:
- addition,
- subtraction,
- multiplication (by a real or by another quaternion, the second of which gives the Hamilton product), and
- division (by a real)).
It also provides conjugation, the norm, and normalization (to a unit quaternion).
It's supplied as
- a generic, to be instantiated with the floating-point type of your choice, and
- an instantiantion using the standard
Float.
The implementation uses Ada 2012 expression functions.
For GNAT, build by gprbuild -P quaternions.gpr.
