Good work locking another thread when you don't want to hear any arguments that might offend your delicate sensibilities. i thought about it. it shed no new light on the current topic at hand, what did you want me to do. tell him "thanks but that's worthless" BS he doesn't say that anywhere. .999 = f(n) = 0 for n >= 0 and f(n) = 9 for n < 0. 1 = f(n) = 0 for n > 1 and f(1) = 1 and f(n) = 0 for n < 1. those functions are NOT the same. so if he SOMEHOW came to that conclusion that they ARE from THAT then he is blind no he locked my thread because he needs some time to grow up, as do you.
