To address this question more comprehensively, I hooked it up to a custom microbenchmarking framework I developed that reduces most of the common "gotchas" to the extent possible. Tests were run in .NE...

Lua的数字只有double型，64bits，你不必担心Lua处理浮点数会慢（除非大于100,000,000,000,000），或是会有精度问题。
你可以以如下的方式表示数字，0x开头的16进制和C是很像的。

Why can't the C# constructor infer type?
... maintain backwards compatibility a ctor on a non-generic type must always win.
Is there a practical reason why the constructor can't support type inference?
Yes. Even if the benefit of the feature outweighs its costs -- which are considerable -- that's not sufficient to have a feature impleme...
