FXT: A Library of Algorithms and a Book

Glad to see it references the two books I have that immediately occurred to me: "Hacker's Delight" by Harry S. Warren and "Combinatorial Algorithms for Computers and Calculators" by Albert Nijenhuis and Herbert S. Wilf.

Oh, nice, there's even a Hartley transform in there [1]

I had no idea it got updates. Impressive. i used it for reference of simple bit level algorithms more than a decade ago
