Fractional USD prices show $0.00

[bthaile]

Fractional prices are not handled in the UI. Example:

$0.00000123 is displayed as $0.00

Need a short hand to display fractional prices, use subscript to indicate number of zeros replaced by subscript, in the above example it would be displayed like

$0.04123

the price would still be compact and tell the user an more accurate price. This formatter can be applied to user token balance as well.
