I guess this is not perfect (in a sense that it is not exactly what you may want), but this was to give you direction.... It gives the butterfly effect for what you wanted... rest of the things... like seeing negative numbers can be played around with... I am not sure what all things are important for you (like mouse over etc)... so I cannot make this perfect unless you tell me what all things are important.
Does that make sense?
yes sunny number format.
