And if you want to give an important hint for the reader of > the code, you can still write comments. When a constant is based on a complex formula, it makes a lot of sense to keep it as it is defined or known. I had many projects (finance, stats and BI related areas) where I would have used constant expressions. As you suggested comments work fine, but do you know what my comments were? The expressions used to generate the constant, sounds double with little to no gain to me. Summary: huge +1 on that. -- Pierre @pierrejoye | http://www.libgd.org
