No Fixed point calculation and floating point executions are diffrent only in the way calculations are preformed. Floating point executions use to take more time than useing fixed point calculations. With todays math coprocessors especially with SSE floating point calculations actually preform well on Intel x86 platform. Fixed point calculations use a fixed decimal place to perform calculations with some performance increases with less precision and accuracy.
