SUMMARY
The infimum of the set of rational numbers with respect to π is definitively 0. This conclusion is based on the fact that there exist rational numbers arbitrarily close to any real number, including π. Therefore, the greatest lower bound of the absolute difference |x - π|, where x is a rational number, is established as 0. This is supported by the properties of rational numbers in relation to real numbers.
