Número π (pi) es la relación entre la longitud de una circunferencia y su diámetro en geometría euclidiana.
About the Irrational Numbers Search Engine:
Why create an irrational numbers search engine? Why not! Built in 2002 just for fun, the original implementation only offered digits for Pi and ran on a makeshift server in my basement. The hardware has since been continually upgraded and the application tuned for performance. Digits for Euler's Number, Phi and the Square Root of 2 were added in 2011 by popular request.
