If one believes that the negation prefix is not a fundamental component of the number being represented, but rather a separate operation, then it's not a stretch to argue that the decimal point is a binary operation and draw similar conclusions about precedence based upon that. The point is that -2^2=-4 looks as silly to me as 2.5^2=2.25 does to you. I find it much more elegant to consider the negation prefix as an inseparable part of the number, just as with multi-digit numbers or decimal points. Irrespective of whatever the chosen standard happens to be, I find it ugly to treat it as 0 - 2^2. And I meant binary, as in two arguments, e.g. 2.5, 2 and 5. |
