Ratio of metallic ratios

Read Original

This article discusses metallic ratios, a generalization of the golden ratio, where the nth metallic ratio M(n) has a continued fraction of all n's. It explains that for large n, M(n) ≈ n, allowing any positive real number to be approximated by a ratio of metallic ratios. The author provides Python code to find metallic ratio ratios that approximate π within 0.001, finding M(132)/M(42) ≈ 3.1412, and proves no smaller pair works. The post is technical, involving mathematical concepts and programming, relevant to IT/TECHNOLOGY.
