Is 1.0 a valid output from std::generate_canonical?
...OI, it would be good for libstdc++ to make this change.
With this change, 1.0 will no longer be generated; instead the boundary values 0x1.fffffep-N for 0 < N <= 8 will be generated more often (approximately 2^(8 - N - 32) per N, depending on the actual distribution of MT19937).

Why do we need boxing and unboxing in C#?
...we can handle one or the other the same way.
Now, back in the olden days (1.0 of Microsoft.NET), there weren't this newfangled generics hullabaloo. You couldn't write a method that had a single argument that could service a value type and a reference type. That's a violation of polymorphism. So ...

Then only atan() of these 21 anchor points was stored. Again, with the help of inverse trig identities, a single M...
