Yes, the decimal representation of pi (π) contains the digit zero.
The Occurrence of Zero in Pi
The question of whether pi contains the digit zero is easily answered: yes. While the exact position of every digit is not known (as the digits of pi are infinite and non-repeating), it has been computationally verified that zeros appear within the decimal expansion of pi. For example, one reference states that the 100-trillionth decimal place of π is 0. Further, other sources confirm the presence of zeros, with some even specifying the position of the first zero. A Reddit post, for instance, indicates the first zero occurs at the 32nd position. [^1]
Multiple sources corroborate the existence of zeros in the decimal expansion of pi. A Quora answer provides the decimal expansion of pi up to the first occurrence of a zero: 3.14159 26535 89793 23846 26433 83279 50. [^2]
It's important to distinguish between the mathematical constant π and the Raspberry Pi, a small computer. The question here refers to the mathematical constant.
Mathematical Properties of Pi
Pi (π) is an irrational number, meaning its decimal representation neither terminates nor repeats. This infinite non-repeating nature means that every possible finite sequence of digits is conjectured to appear somewhere within its decimal expansion. This conjecture is based on the assumption that pi is a normal number, which is an unproven property.
