您要查找的是不是：
- arithmetic constant expression 算术常数表达式
- Is a constant expression that can reference variables. 是可以引用变量的常量表达式。
- Is due to its syntax expected to be a constant expression. 被当成了一个常量表达式。
- For example, the initializer of an enumerator must be a constant expression. 例如，枚举成员的初始化式必须是常量表达式。
- Any constant or constant expression that evaluates to the data type of the parameter. 任何计算为参数数据类型的常数或常数表达式。
- Provided the value of the constant expression is within the range of the destination type. 前提是常数表达式的值处于目标类型的范围之内。
- A constant expression is an expression that can be fully evaluated at compile time. 常数表达式是在编译时可被完全计算的表达式。
- In a checked context, a compile-time error occurs if the operation is a constant expression. 在所检查的上下文中,如果该运算是常数表达式,则发生编译时错误。
- The absorption rate constant expresses the speed of absorption. 吸收速率常数表示吸收的速度。
- Generally speaking, a constant expression is an expression that the compiler can evaluate at compile-time. 一般来说，常量表达式是编译器在编译时就能够计算出结果的表达式。
- Name of the variable to assign the value. Any constant expression is allowed for this attribute, not only literals. 变量将要使用的变量名。允许使用任何常量表达式而不只是文本值。
- A constant expression must yield a value of the target type, or of a type that can be implicitly converted to the target type. 常数表达式必须产生具有目标类型或者可隐式转换为目标类型的类型的值。
- Statement might not accept the data type you want to assign, or you might not be able to compute the value at compile time with a constant expression. 语句可能不接受要赋给它的数据类型,或者在编译时可能无法使用常数表达式计算值。
- We may supply an initial value for one or more enumerators. The value used to initialize an enumerator must be a constant expression . 可以为一个或多个枚举成员提供初始值，用来初始化枚举成员的值必须是一个常量表达式。
- As a consequence an enumerator is itself a constant expression and so can be used where a constant expression is required. 枚举成员本身就是一个常量表达式，所以也可用于需要常量表达式的任何地方。
- Nontype template arguments must be compile-time constant expressions. 非类型模板实参必须是编译时常量表达式。
- When a function template is instantiated, each nontype parameter is bound to a constant expression as indicated by the arguments used in the call. 在实例化函数模板的时候，将每个非类型形参绑定到一个常量表达式，该常量表达式作为调用中使用的实参给出。
- precision of real arithmetic constants 实算术型常数的精度
- The little boy was not good at arithmetic. 这个小男孩算术不太好。
- When blood pressure quick heighten appearsHypertensiveWhen danger is resembled, constant expression is recognizant obstacle. 当血压急剧增高出现高血压危象时，常表现为意识障碍。
