Lispology

One of the most useful Common Lisp functions for text processing is search; it lets you search for a substring in a string, and returns its position.

One of the examples I wanted to include for my Simple infinite precision arithmetic package is a function to calculate an arbitrary number of digits of π.

This is a simple infinite precision arithmetic package I wrote as an example program for my Lisp interpreter for small microcontrollers, uLisp.
