Programming Notes
A Bisenary Number System
Last updated: November 2013
A guided project to switch integer representations between base10 and base36 number systems. A JavaScript applet is provided for the conversion from decimal to bisenary.
Testing Primes To Nine Quadrillion
Last updated: January 2012
Primality testing algorithm based on MillerRabin test to the bases 2, 3, 5, and 7. Written in JavaScript, where integer upperbound is 53 bits.
Trial Division To Twelve Digits
Last updated: December 2011
JavaScript factorization program for integers up to one trillion, using trial division by prime numbers from 2 to 999,983. (Note: While these notes have not been updated, the prime database has recently been expanded to 10^7, so we can now factor integers up to 14 digits.)
