您要查找的是不是：
- integer constant expression 整型常数表达式
- Rem. 58 The integer constant 0 may be cast implicitly to any pointer type. 整形常量0可以隐式地转化为任何一种类型的指针。
- 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。
- Is a pre-defined integer constant that instructs the container to process the rest of the page. 是一个预定义的整型常量,它指示容器处理页面的剩下部分。
- Appending a 0 (zero) to a literal integer constant causes it to be interpreted as octal. 在整型文字常量前面加一个0，该值将被解释成一个八进制数。
- We can write a literal integer constant using one of three notations: decimal, octal, or hexadecimal. 定义字面值整数常量可以使用以下三种进制中的任一种：十进制、八进制和十六进制。
- 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。
- Appending either 0x or 0X will cause a literal integer constant to be interpreted as hexadecimal. 而在前面加一个0x或0X，则会使一个整型文字常量被解释成十六进制数。
- For example, 'abc' is a character string constant, 123 is an integer constant, 'December 16, 1999' is a datetime constant, and 0x02FA is a binary constant. 例如,“abc”是字符串常量,123是整数常量,“December 16,1999”是datetime常量,而0x02FA是二进制常量。
- 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。
- Integer constants must be whole numbers; they cannot contain decimals. integer常量必须全部为数字;它们不能包含小数。
- 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。
- Integer constants are the numbers you type directly into your sketch, like 123. 整数是你直接写入程序中的数字，象123一样。
- 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。
- Note that the result is always floating-point (Double), even though both operands are integer constants. 请注意,即使两个操作数都是整数常数,结果也始终为浮点类型(Double)。
