Hi, dunno if D maybe already uses something like that, but I just stumbled upon this article and thought it may be of interest: http://www.serpentine.com/blog/2011/06/29/here-be-dragons-advances-in-problems-you-didnt-even-know-you-had/
The article claims that the discussed algorithm is about 5 times faster than what the GNU libc uses in printf. Cheers, - Daniel
