: Good early morn;
I am studying Perl on my own and have come to a halt. I understand that the ** means to the power of for instance 2 ** (3 ** 4) = 2 ** 81 then when I solve the next step and come up with a very large number 2417851639229258349412354.
The answer that shows in the book on the same page is 2.41e24. I get how they came up with the 2.41 and I know that the e stands for (times 10) the next step is where I am lost. My Question is
How would I figure out a problem such as this?
Basically I would like to know the steps in solving the ending.
I would truly appreciate the Help. Thank-You ahead of time.

The part "e24" stands for times 10 to the 24. So if you have

2.41e24

it really looks like

This will turn 2.41 into a very large number with 22 zeros. So in other words the decimal moves to the right 24 times.

So if you have

2417851639229258349412354

Start at the very right digit and place a decimal after the "4" so it reads

2417851639229258349412354.0

Now move the decimal incrementally to the left (make sure you count how many steps it takes) until you get in between the first and second digits like this:

2.417851639229258349412354

So you should've counted 24 places, which came from "e24".
