Rounding: Reduces a "precise" index number to an integer. 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: +3.000 remains +3.
Truncating: Reduces a "precise" index number to an integer. When Truncating, we simply take away (truncate) the decimal part of the index number, leaving only the integer part. Examples: +2.95 becomes +2, +2.15 becomes +2, -0.99 becomes 0, -3.05 becomes -3. Of course, an index number which has been calculated to be "precisely" an integer, does not change: +3.000 remains +3.
Flooring: Reduces a "precise" index number to an integer. When Flooring, all the index numbers are taken down ("floored") to the nearest smaller integer. Examples: +2.95 becomes +2, +1.05 becomes +1, +0.10 becomes 0, -0.05 becomes -1, -3.99 becomes -4. (Notice that flooring positive numbers is identical to truncating them.) Of course, an index number which has been calculated to be "precisely" an integer, does not change: +3.000 remains +3
