Why we don't make fractions more than binary for computers ???(read the details complete)?

note like quantom computers.i mean some thing more than on %26 off. for example 0=no voltage 1=0.1voltage 2=0.2voltage .....10=1voltage. a fraction that explains something more than on %26 off for hardware and software. building new hardwares designing new programs. its a difrent fraction and dont works like binary fraction. logicaky it has more thane two chioces(on off)and works smarter. we can make complex codes on this system works smarter.the memory gets biger...... and something more than computers than now we have

voltage fluctuations and outside interference will affect the outcome of the number. An example would be adding 2 numbers, say 3 + 4. If 3 is represented by .3V and 4 is represented by .4V, somewhere between there you have to have a dividing line. Say 3 is anything between .25V - .35V and 4 is anything between .35V and .45V. If you have voltage fluctuations or interference of just .05V, the number could be interpreted wrong.

With digital (1 or 0), the voltage to represent 0 is usually around 1.2V or less, and a 1 is represented by 2.5V or more (assuming 5v source). Noise and fluctuations will not be great enough to affect the outcome.

Someone else also made a good point that most data is stored magnetically (even optically would be difficult), and would be near impossible to store anything other than a 0 or 1.
