I have noticed that the folks here who prefer to calculate their percents using the 28.05 * 1.15 method don't really have a dog in this fight as to how Calculator's % key behaves. These same users say they don't like and don't even USE the % key, so logically, it should be no skin off their noses if part of the world prefers the % key to "do the math" for a user who actually USES that key. Not that free discussion of all sides shouldn't happen, but I get the feeling that the folks who like the % key to simply move the decimal point two places are having their sense of mathematical purity offended, and that they need to DEfend and teach and instruct the rest of us in the "right way" to use the % key which they themselves don't even use. No matter how the % key behaves, you are in no way prevented from calculating your percents however it pleases you to do so. The order of operations is there, the decimal key works for you, as do the parentheses, the 4 basic function keys as well as the = key. You are free to uphold your vision of mathematical purity. The rest of us simply want the % key (which you don't even use) to behave as it once did. nk
