Rounding ( blackjack)

A practice which reduces every "precise" index number to just an integer (Rounded indices, or indexes). When Rounding, all the index numbers are rounded to the nearest integer, following the mathematical rules which apply when rounding numbers. Examples: -1.50 becomes -2, -1.49 becomes -1, -0.50 becomes 0, +0.49 becomes 0, +0.50 becomes +1, +1.49 becomes +1, +1.50 becomes +2. Of course, an index number which has been calculated to be "precisely" an integer, does not change: +3.000000 remains as +3. Also Flooring, Truncating.
