Fixed vs. Floating-Point Math

Windows Mobile 6.5

Generally, it is much faster for the Windows Mobile device CPU to use fixed-point math instead of emulating floating-point math. Therefore, the design of the Direct3D Mobile library supports both number types.

Since the Windows Mobile Version 5.0 release, Direct3D mobile has supported fixed-point math.
