Dear,
LPC3180 is a ARM9 Based uController. Usually ARM Based uControllers have
FPU.I don't want to use ARM based uControllers because this makes my circuit
much more complex.

Well, I do not know about any ARM7 that would have an FPU and not about any other ARM9 having a FPU. Don't know where you got your information about ARM "usually" having floating point.
If an ARM makes your circuit too complex you really should think about converting to integer instead of using floating point.
Just my 2 cents, Robert
