Talk:Power of two
From Wikipedia, the free encyclopedia
It says "nonnegative integer" in the article. Now, 0 is the first nonnegative integer, 1 is the second, 2 is the third, 3 is the fourth, etc. However, 8, which corresponds to the exponent of 3, is thought of as the third power of 2, not the fourth, and 1 is thought of as the zeroth. Any modifications to the first paragraph of the article?? Georgia guy 21:05, 8 Jan 2005 (UTC)
- This is kind of tricky. In common parlance we say that a is the cth power of b if a = bc, even if it is not the cth in a list of nonnegative powers of b. I've even heard people say "the one-halfth power" for the square root. It's a bit sloppy, and maybe we can rephrase it, but it's pretty common. Deco 02:54, 11 Jan 2005 (UTC)
[edit] Categories for binary number algorithms
I think rounding to nearest power of two number should be put to some algorithm/computer arithmetic category, or even some other article. Rounding to nearest power of two is often related to computer programs and it would make sense to have some article/category listing the relevant methods. Any ideas which category/article?

[edit] First forty-one powers of 2
This phrase can be reworded as "first through forty-first", not "zeroth through fortieth". Any faulty thinking?? Georgia guy 21:06, 21 October 2006 (UTC)
