Can someone give me a explanation of the matematical constant e=2.7182...??? What''s so magical about it and why is it exactly 2.7182...??? If you know of some resources where I can get more information then that would be great too! Thanks!

Real programmers don''t document, if it was hard to write it should be hard to understand

::shifty eyes:: you''re a non-believer aren''t you? e shows up nearly everywhere. e and ln (log base e) determine the halflife of an atom, how long it will take an object to cool to a certain temperature, etc (anything where the amount at a time is based on the rate of change of the amount). That is not nearly the limit of where it shows up but I am in a hurry so just go to the link given already. Wikipedia.com also has some good info on it but the site was down when I tried to get onto it this time.

pi > e

I''m sorry, it had to be done.

PI >> e

I coudn''t resist either, even though it has nothing to do with OP.

You have to remember that you''re unique, just like everybody else.

definiton of e?

e=(1+(1/x))^x where x starts at one and goes forever. use like a large nubmer for x. say...20. You''ll get an answer
the larger x is, more accurate e is.

I guess he wants to know exactly why e appears everywhere, rather than what it is. Precisely how he said it, why it''s so "magical"

You know skybin.. e has many other definitions. e can also be defined as the other boundary besides 1 under the graph of ln(x) such that the area under that curve is equal to 1. The second would be the sum of x/x! from 1 to infinity

Also, the derivative of e^x is..... e^x !!

that sounds pretty cool to me!
