How would I round a calculation in a template in DBManSQL?

My calculation is as follows:
<%MSRP - $Price%>

This takes "Retail Price" minus "Sales Price" and returns "YOU SAVE" value.
It does the calculation correctly, but occasionally produces a long value.
ex. $8.72000000000001

See an example here:

I want to round to the nearest currency decimal.
ex. $8.72

Any help would be appreciated!

Thanks,

Rick
