Irrationality measure
text:
In mathematics, an irrationality measure of a real number α is a measure of how "closely" it can be approximated by rationals. If a function f, defined for positive real numbers, strictly decreasing in both x and λ is given, consider the following inequality: 0 < | α − p q | < f for a given real number α ∈ R and rational numbers p q with p ∈ Z, q ∈ Z +. Define M as the set of all λ ∈ R + for which only finitely many p q exist, such that the inequality is satisfied. Then λ = inf M is called an ir
