Re: value of 'e'

Hi;

The most important constant in mathematics, even more so than pi. Called Euler's number even though it was discovered by one of the Bernoulli's.

When you substitute x = 1 into the following sderies you get e.





To see much more go here:

e has special meaning to me because it was what got me started. I saw this article in Byte magazine by the legendary Steve Wozniak.

In what way?

Really? how?

I fell in love with getting digits of constants.

Re: value of 'e'

well,i was calculating the value of 9^9^9 which contains several million digits.
it is said that it would take around a year for a person to really read that entire number.

Re: value of 'e'

Hi,

9^9^9 has

digits, which would take much more than a year to read!

It is large but you can still do calculations on it.

Try to get the first 10 digits if you can.

That is the first digits of e, I have given her a tougher problem.

Get the first 100 digits of 9^9^9 which should be easy for you.

Re: value of 'e'

Does it mean 9^(9^9)?

Are you asking for 9^(9^9) mod 10^100

Re: value of 'e'

Yes, it means 9^(9^9).

Nope, that would get the last 100 digits.
