... to 100 percent exactly. (If a number ends in a 5 that must be rounded, our rule is to round to the nearest even digit, but a high-speed com- puter often has views of its own about this, since it may produce 2.5 as 2.4999999, depending on just how it carried out the calculation. Consequently, we set...
