Since this is not a 'standard' in formatting, I would write a function, and then use formulas to call the function to display the value. this way you only have to determine the logic of the function 1x.
Now what would a function look like? That would be an interesting problem.
1) you need to determine how many decimals to move
a) account for the sign--might be negative
2) rounding to only 2 decimal places
3) returning the string
not too hard, but challenging enough. give it a try.
