## Error in Exponentiation

## Error in Exponentiation

(OP)

Folks,

I am trying to generate Mill's Primes and the code is very simple.

For K = 1 and 2, the program gives the correct answers of 2 and 11.

But, for K = 3 it gives 1359 with the M value specified.

According to the maths (and Excel), the correct answer should be 1361 - the 3rd Mill's Prime.

I fail to understand where my calculation is going wrong.

Can someone please help.

Great help.

I learned something new from you again

As a former mathematician, I've never heard of Mill's prime numbers or those constants - almost unbelievable. I only read about it yesterday on Wikipedia: https://en.wikipedia.org/wiki/Mills%27_constant

I studied math and taught in a college for about 6 years. But I was mostly into numerical mathematics, differential equations, optimization, and statistics. Number theory has never been an area of interest to me.

A kindred spirit.

Studied maths at uni but never enjoyed it.

Too many exams and too much pressure.

Now I enjoy it thoroughly (along with Physics).

My main interests are in Prime Numbers and Cantor's Infinite Set theory.

I also enjoy Linear Programming and use Excel's Solver to keep in touch.
