It tricked all the engines, and even itself.

A followup post provides code to take advantage of that improvement. This post tries to make Algorithm D approachable, and also has an idea for an improvement, in the last section.
I am optimistic that these ideas are original. This post presents a narrowing division algorithm, improving upon the widely used “divlu” function from Hacker’s Delight. Last post explored Algorithm D, and some improvements for the 3 ÷ 2 = 1 digit case. Labor of Division (Episode V): Faster Narrowing Division April 29th, 2021.It works by replacing divide instructions with cheaper multiplications and shifts. Libdivide is fish’s library for speeding up integer division by runtime constants. Benchmarking division and libdivide on Apple M1 and Intel AVX512 May 12th, 2021.Angband is a venerable roguelike dungeon-crawler set in the Tolkien universe. At the bottom are some benchmarks.Īnnouncing a port of Angband running entirely in-browser. It presents an alternative derivation of the improved correction step, and shows how the true remainder may be computed from the estimated remainder. Last post presented a narrowing division algorithm, but left some questions dangling around the interpretation of intermediate values.
