# Pi and Other Constants:

## Online Papers:

The following papers concerning computation of various
familiar transcendentals are available in pdf. Paper P123 details how to compute,
among other things, individual binary digits of Pi. Fortran code for this is available below. The first paper is an expanded HTML version of P40.
