2025-12-15 10 Million Digits of π with Multi-Scale Structure Analysis doi:10.57760/sciencedb.33068 en This dataset contains approximately 10 million decimal digits of π, with analysis of multi-scale cyclic nested structures. Key discoveries include: a 153.8-digit period ≈ 49π (0.09% error), a 487.8-digit period = 2×244-digit framework, and alignment of sub-periods with the Fibonacci sequence. Statistical validation shows significant non-randomness (p < 0.001) while supporting the normality hypothesis (p = 0.79). pi; mathematical constants; number theory; digital sequences; periodicity; structure analysis; dataset pi; dataset Fu,Wenju PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
