afaik, based on conversations with a number of developers, this is not correct. Internal processing math depends on the algorithms and routines coded by the application developer, not through some default of the cpu or the OS - you can still run fixed point math routines using floating point cpu's after all - although the architecture of the OS and cpu can definitely influence what type of routines will run more efficiently and stably.
