I need help identifying this real number. The closest I have gotten is e+pi/4.

But I think it has something to do with the Zeta function?

Please help.

Thanks

Where did you find this number?

It was asked by my professor as HW, but I have looked and looked and can not find anything online.... I was wondering if anyone else knew where to look or even how to look?

Thanks.

Identify This Real Number

Then maybe you should give more information on what class you are taking and what subject you just covered.

It's just a programming class, so the question isn't all that relevant. Not exactly sure why he asked us this question, but he did. I was trying to use an online inverse symbolic calculator or something, but I just can't find anything.

Off hand there doesn't seem to be anything special about this number.

The class and subject question certainly is relevant and has everything to do with it.

Have you converted to binary and noticed anything?

The presentation of the number as a real is noteworthy because machine operations can't work with reals... maybe the idea is to get you thinking about computable vs real numbers?

Have you noticed it interesting that a 23 digit base 10 number does not have an instance of 2?
Maybe this is a clue to look at the method of compliments?

Or it may be like the version of 20 questions where one only pretends to pick something, but keeps all answers consistent with previous answers. Just to see where it goes?

And what do you get if you compute e+pi/4 to 22 decimal places?

What you've said is really intriguing. Please expand.

Is it? Seems like an 8% chance, and similarly for any other nonzero digit. So it's not that surprising that some digit doesn't feature.
method of compliments?
Flattery will get you nowhere.
