What's 9 in base pi?

[–] [email protected] 16 points 1 month ago* (last edited 1 month ago) (1 children)

9 (the base pi number) doesn't exist because all digits must be less than pi. 9 (the base 10 number) is apparently roughly 22.2021120021 in base pi.

Edit: a bit of explanation for that last one, it's because 2π + 2 + 2/π + 2/π^3^ + 1/π^4^ ≈ 8.99

Technically they didn't specify what number their use of the symbol '9' represents!!!!!

They wanted to know how to represent 6, but displayed upside down.

would all integers necessarily be irrational in base π?

[–] [email protected] 6 points 1 month ago (1 children)

Except for 0, 1, 2, 3.

Integers are necessarily irrational because π is transcendental and not an algebraic number.

how are you defining irrational? the definition i know is not base dependent.
