I would like to illustrate some limitations with floating point calculations.  Can I force Mathematica to do floating point computations at a standard float size and the display the full results (as the same size float)?

E.g., if I enter
0.1+0.2
I would like to see
0.30000000000000004

Thanks,
Alan Isaac
