This wasn't merely a single typo, but the OP either being sloppy or possibl= y thinking important details like this don't matter. In other words, it wasn't just a oops (despite the OP's protestations later), but a irresponsibility. That sort of thing must not be let pass here, especially in cases like this where the subject is well within the domain of the list. I was expecting that if the OP didn't notice the mistake from my comment that he'd come back with "why do you say weeks" or some such. Eventually h= e would have realized he said 20e6 seconds instead of 20e-3 seconds as he apparently meant. The more drawn out this process, the more forcefully the lesson would be learned. Of course around here some third party apologist always steps in and short circuits the process before it can run to completion, so you get what you asked for sooner rather than later at the expense of the educational value. Units matter. And no, I'm not going to let things like this slide in cases where I think it's more than just a one off typo. After all, all I did was respond correctly to exactly what was asked. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
