Yep, my idiocy. As if I am the one bent out of shape that 29.87 gets rounded to 30. After all this, that is the point you wish to make. Gee, you are really scoring big points.
I'm certainly not "bent out of shape" about it but merely stating that whatever the FairTax rate figure ends up being in the bill, it should be - when calculated as t-e - calculated correctly and carried out to two decimal places if it does not come out to an integer.
No point in being sloppy like the SQL crowd.
