为可空类型提供类库支持，包括转换运算符和算术运算符。
Library Support for nullable types, including conversion operators and arithmetic operators.
封送处理的布局可能不同于内部布局，因此在使用size of运算符时，我已经描述的类型可能(实际上是非常可能)报告不同的结果。
The marshaled layout could be different from the internal layout, so it's possible (and, in fact, probable) that the types I've described will report different results when using the sizeof operator.
如果需要，可以使用instance of运算符来确定指定的目的地子类型。
If required, the instanceof operator can be used to determine the specific destination subtype.
为了在结构化类型的实例上调用mutator或observer方法，请使用双点(. .)运算符(清单1、清单2和清单3)。
To invoke a mutator or observer method on an instance of a structured type, use the double-dot (..) operator (Listings 1, 2, and 3).
E4X是一个草案标准，为ECMAScript语言增加了原生XML数据类型，为常见的 XML操作提供了运算符。
E4X is a standard that adds native XML datatypes to the ECMAScript language and provides operators for common XML operations. To quote the E4X specification page
接下来选择运算符”isgreaterthan“，最后类型”Number“值为 0.0的被选择为最后一个条件。
Then the operator "is greater than" is selected and finally the type "Number" with value 0.0 is selected for the last term.
这取决于你在做什么类型的运算。
总的来说，如果一个函数内的所有运算都可以处理某一类型，这个函数就适用于这一类型了。
In general, if all of the operations inside a function work with a given type, the function works with that type.
即使对于版本7.2，如果其中一个运算对象被明确声明为浮点类型，那么Vim只支持浮点算术。
Even under version 7.2, Vim does only floating-point arithmetic if one of the operands is explicitly floating-point.
这类似于适用于integer、decimal、float、double或其混合类型的加法运算符(“+”)，也类似于面向对象中的多态性。
This is similar to having plus operators (" + ") that apply to integers, decimals, floats, doubles, or a mix of these types. This is also similar to the polymorphism found in object orientation.
总之，在元组元素的运算上几乎同态问题比同态问题更复杂些，并且它扩充了范畴数据类型变换的应用范围。
In brief, almost-homomorphism is more difficult than homomorphism on the operation of the elements of tuple, and it extends the application area of CDT translation.
