Need suggestions on the best 32 bit microcontroller. I need to select a suitable microcontroller which can support more than 3 digits floating point accuracy.

All 32-bit uC can manage that. A more important question is how many fp instructions/s you need to crunch. That affects if you need hardware FP or if emulation is ok.
Another thing: You say 3 digits. I assume you mean 3 decimal digits. 1.23e7. That is a puny precision. That is way less than the 32-bit IEEE single-precision FP.
With so little precision, you may not even need FP but may look into 32-bit fixed-point numbers.
Edit: Remember that when using FP or fixed-point, it isn't enough to think about precision. You must also specify required range, i.e. how small/large exponent you require.

Even an 8051 could manage that!
Thank you all for the replies. I would go for ARM7 (LPC series). Where can I get the getting started tutorials. What development facilities must be possesed by a beginner.
