Description 
This module corresponds to section 2.2 (Primitive Types) of the OpenAL
Specification and Reference (version 1.1).


Synopsis 




Primitive Types


As OpenAL is meant to allow for seamless integration with OpenGL code if
needed, the OpenAL library primitive (scalar) data types mimic the OpenGL
data types. Guaranteed minimum sizes are stated for OpenGL data types, but
the actual choice of C data type is left to the implementation. All
implementations on a given binary architecture, however, must use a common
definition of these data types.


FloatingPoint Computation


Any representable floatingpoint value is legal as input to an OpenAL command
that requires floating point data. The result of providing a value that is
not a floating point number to such a command is unspecified, but must not
lead to OpenAL being interrupted or terminated. In IEEE arithmetic, for
example, providing a negative zero or a denormalized number to an OpenAL
command yields predictable results, while providing a NaN or infinity yields
unspecified results. Some calculations require division. In such cases
(including implied divisions required by vector normalizations), a division
by zero produces an unspecified result but must not lead to OpenAL
interruption or termination.
