I love that you used such a simple example to show what kind of errors can occur based on how one person reads vs. another (vs. a computer). The same can be said with some of the code I saw last year: cfif x AND y AND z OR a AND b OR c AND d WTF? cfif (x AND y) AND (z OR ( a AND b) OR (c AND d)) Ah. Ok.

Ah. Ok.

I always use parentheses not only do I prefer explicit precedence, I believe it's much easier to interpret the code to the human eye. While "3 + 4 * 5" may behave like you intended, it's too easy to accidentally interpret this as "(3 + 4) * 5" when you looking at the code. Explicitly writing the code as "3 + (4 * 5)" makes it very clear on the intend formula. This hold true for operators as well... Good post.

While “3 + 4 * 5″ may behave like you intended, it’s too easy to accidentally interpret this as “(3 + 4) * 5″ when you looking at the code. Explicitly writing the code as “3 + (4 * 5)” makes it very clear on the intend formula.
