Walter thanks for the updates!
In testing my D v1.0 project source code, I found that two functions were removed between v1.028 and the v1.029 releases, the bool isPosZero(real) and bool isNegZero(real) functions that were in std.math. Since D v1.0 shouldn't be changing much, and just mainly bug fixes for the most part, I normally wait a few releases before testing my code against them. Thus looking at std.math I see a lot of nice improvements, but feel the non-private labeled functions should remain in now that D v1.0 as been reached.
A two simple wrapper functions should be put back in so existing D v1.0 code doesn't break...in this case of course I could simply add in replacement functions for these in my own code. But the point being that functions should not be removed at this point.
I think the following code could replace these two functions using the new changes found in std.math:
bool isPosZero(real x)
{ return isIdentical(x, 0.0); }
bool isNegZero(real x)
{ return isIdentical(x, -0.0); }
Thanks, keep up the good work!
