Is Pi - π a palindrome?

Question

Till yesterday, I knew π as an irrational number. But I accidentally saw a blog, which says thatπ is a palindrome, ending in the decimals 51413. Is Pi is a palindrome, not an irrational number? Whether it is irrational or not, can you pls prove in simple method?

Answer 1

Do not let that confuse you. You were right, $\pi$ is an irrational number with an infinite number of decimals, which means that it never ends. Maybe the guy in the blog truncated the decimals at some point or something, but saying that pi ends with anything is just wrong.

Answer 2

No, $\pi$ is not a palindrome. It is irrational. Its decimal expansion continues forever and so it has no last digits.

Answer 3

No it is not. For more information on that I recommend this article: The Last Digit of Pi
