The result of the following project was added to the standard release in 2.8.


Goal of this project was to improve the speed of LargeInteger arithmetics.

Areas of interest for this speed up are

I've just (Tue Dec 7 03:24:43 CET 1999) compiled my first very simple example plugin and want to start with a LargeIntegers project now; goal is

Example and timeline: I want to improve the computation of
(1000 factorial) by factors of
before the Y2K.

The main implementation idea is to use the current implementation of LargeInteger arithmetics in Smalltalk (as far as possible and convenient, we'll see...) and to convert it into simple Smalltalk and then in a C plugin.

Further enhancements seem to be possible. – Stephan Rudlof
