表达式是否合法取决于操作数的类型，而且合法的表达式其含义也由其操作数类型决定。
The type of the operand (s) determine whether an expression is legal and, if the expression is legal, determines the meaning of the expression.
如果您不知道一个命令处理的操作数类型，fish在许多情况下可以提供帮助，但并不是在所有情况下都可以。
If you don't know what kind of operand a command manipulates, fish can help-in many cases, but not all.
如果要强制取得浮点结果，则必须确保操作数中至少有一个为浮点类型。
If you want to force a floating-point result, be sure that at least one of the operands is a floating-point type.
这会导致其他操作数也被转换成64位的类型，这样在对表达式进行赋值时就不需要再进行转换了。
This will cause the other operands to be promoted to 64-bits and no further conversion is needed when the expression is assigned.
这就允许数据联合服务器接收对集成视图的查询和计算要执行的最优子操作数量和类型。
This allows the data federation server to receive queries against the integrated view and to calculate the optimum number and types of sub operations to perform.
简单的答复是，Python会根据需要将表达式中的所有操作数转换为最复杂的操作数的类型。
The simple answer is that Python converts all operands in an expression to the type of the most complex operand, as necessary.
specific intrinsic 的所有操作数都会映射为一个称为qword 的特殊类型，它实际上是一个opaque寄存器值类型。
All operands to specific intrinsics are cast to a special type called qword, which is essentially an opaque register value type.
如果在表达式中混合使用无符号和有符号的32位整数，并将其赋值给一个有符号的long类型，那么将其中一个操作数转换成64位的类型。
In cases where unsigned and signed 32-bit integers are mixed in an expression and assigned to a signed long, cast one of the operands to its 64-bit type.
对于athrow指令，可以使用FindBugs的Op codeStack帮助器类来了解athrow操作数的类型。
For the athrow instruction, you use FindBugs' OpcodeStack helper class to learn the type of the operand of athrow.
将一个操作数包装到number 、boolean 、string或者其他新增的类型构造器函数中。
Wrap one of the comparands in number , Boolean , string , or one of the new type-constructor functions.
对于类型转换运算符，操作数或返回类型必须是类或结构的数据类型。
For a type conversion operator, either the operand or the return type must be of the data type of the class or structure.
否则，左操作数是早期绑定的整型数据类型，并且不执行强制。
Otherwise, the left operand is early-bound integral data type and no coercion is performed.
程序量是一种以代码中运算符和操作数为基础的度量方法，表示理解某个类型或方法的难易程度。
Program volume is a measure of the difficulty of understanding of a type or method that is based on the number of operators and operands in the code.
唯一的限制是用于给定的操作码的操作数的类型之间的一致性。
The only constraint is about coherence between the operand type used for a given opcode.
如果操作数的数据类型不同，那么，较多的数据类型将被计算采用。
If the operands are of different types, the "larger" type is used for the calculation.
然后确定一个公共类型，把操作数转换为该公共类型，这次运算的结果就是该公共类型。
Then you determine a common type, convert the operands to the common type, and the result of the operator has that common type.
泛型允许类，结构，接口，代理还有方法被他们存储和操作数据类型参数化。
Generics permit classes, structs, interfaces, delegates, and methods to be parameterized by the types of data they store and manipulate.
比较的过程是计算每个操作数，然后根据需要将操作数转换为相同的类型。
Comparisons are then made by evaluating each operand, and converting them as needed, so they are of the same type.
点操作符仅应用于类类型的对象：左操作数必须是类类型的对象，右操作数必须指定该类型的成员。
The dot operator applies only to objects of class type: the left-hand operand must be an object of class type; the right-hand operand must name a member of that type.
因此减号操作符的运算结果类型依赖于操作数被提升之后的类型。
The result of the unary - operator is the negative of its (promoted) operand. The integer promotions are performed on the operand, and the result has the promoted type.
如果操作数相互不兼容，将强迫使它们成为适当的类型。
If operands are not compatible with each other, they will be coerced to the appropriate type.
请确保操作数的数据类型适合于运算符，且顺序正确。
Be sure the data types of the operands are appropriate for the conversion, and in the correct order.
在磁盘阵列中，为了提高I/O性能，减少I/O执行时间，采取了将分解到同一磁盘上同命令类型且操作数据地址相邻的多I/O命令合并的策略。
In order to improve I/O performance and reduce I/O implementation time, a kind of command combination strategy is used.
