The compiler could infer that t is Integer, Number, Serializable, or Object, but it chooses Integer as that is the most specific type that fits the constraints.
编译器能够推断t是Integer、Number、serializable或object，但它选择Integer作为满足约束的最具体类型。
The REF USING INTEGER clause specifies that the INTEGER data type will be used to represent the REFERENCE type of this structured type and all of its subtypes.
REF USINGINTEGER子句指定了 INTEGER数据类型，将使用这个数据类型表示该结构化类型及其所有子类型的 REFERENCE 类型。
The script "num" we defined earlier has the type script because it is a function that when executed yields an integer value (in this case the integer 42).
我们早先定义的脚本“num”具有Script类型，这是由于它本身就是一个在执行时会生成一个整数值的函数(在这个例子中，这个整数值是42)。
The key isn't restricted to being an integer; it can be any nonmutable data type, including an integer, float, tuple, or string.
键并不限制为整数；它可以是任何不易变的数据类型，包括integer、float、tuple或string。
Unfortunately, the Standard permits an implementation to make all of the integer types the same size, and that complicates the rules for when a signed integer type meets an unsigned integer type.
不幸的是，标准允许实现使得所有整数类型都是同样的大小，这使一个有符号整型遇到一个无符号整型时的规则变得复杂了。
If the unsigned integer type has rank greater than or equal to the rank of the signed integer type, the common type is the unsigned type.
如果无符号整型的优先级高于或等于有符号类型，公共类型是无符号类型。
A floating literal consists of an integer part, a decimal point, a fraction part, ane or e, an optionally signed integer exponent, and an optional type suffix.
浮点文字量由整数部分，小数点，小数部分，e或e，可选的有符号整数指数，以及可选的类型后缀组成。
On the other hand, if the first join column is an integer, the related join column must also be of an integer data type, but it can be a different size.
另一方面，如果第一个联结资料行为整数，则关联的联结资料行也必须为整数资料型别，但资料大小可有所不同。
On the other hand, if the first join column is an integer, the related join column must also be of an integer data type, but it can be a different size.
另一方面，如果第一个联结资料行为整数，则关联的联结资料行也必须为整数资料型别，但资料大小可有所不同。
