WebJul 8, 2024 · Essentially, just as @charlus said - you define a sequence of rational numbers that converges to the irrational number you are interested in, and take a limit of the principal values. For example, if we had π, and a sequence of rational approximations of it π n: π 1 = 3 1, π 2 = 31 10, π 3 = 314 100... By construction it converges to π.
