A primitive type, or a built-in type, is a special type that differs from a class in Java. They are the most frequently used types in our programming. Java is a strongly typed language, and the first declaration of a variable must describe the data type, and the first variable assignment is called the initialization of the variable.1.

precision. In the literal 0.1 is an example of such.The Oracle database provides two numeric data types that are designed for floating-point numbers:Binary_floatThe Binary_float is a 32-bit, single-precision floating-point numeric data type. can support at least 6 bits of p

Search for the article content from the Internet and sort it out.(1) Char, varchar, text and nchar, nvarchar, ntextChar and varchar are both between 1 and 8000 characters in length. The difference is that char is a fixed-length character data while varchar is a variable-length character data.The so-called fixed length is fixed length. when the length of the input data does not reach the specified length, it

There are 5 simple data types in ECMAscript, also known as basic data types: Undefined, Null, Boolean, number, and string. There is also a complex data type of--object.Undefined typeWhen you declare a variable with VAR but do not initialize it, the value of this variable is

(excluding decimal points) of the value to be stored, the default value is 0, and s represents the number of digits after the decimal point.For example: Decimal (15 5), which represents a total of 15 digits, where the integer is 10 bits, and the decimal number is 5.4, NUMERICThe numeric data type is exactly the same as the decimal data type.NOTE: SQL Server supp

point anywhere from the first to the last number, or you can have no decimal points at all. The exponent may (optionally) be used for the following number of increased ranges (for example, 1.777e-20). Scale values do not apply to floating-point numbers, because the number of digits that can be displayed after the decimal point is unrestricted.The number of binary floating-point values is stored internally by the Oracle database. Stores a value using fractional precision numbers. The exact same

recommended type is provided, the database will store the data according to the recommended type. the data type that is preferentially used is called "affinity type ". In sqlite3.0, each column in the database is defined as one of the following affinity types: Text Number Integer None A column with type affinity stores all

comparing a character value with a NUMBER value, Oracle converts the character data to NUMBER. When comparing a numeric value with a numeric value, oracle implicitly converts the numeric value to a numeric value. For example Assume that the

unsigned integer, or it can be assigned using integers, but the integer range is between 0~65535, such aschara=78; Denotes capital letter ' N '4. Boolean type:The Boolean type has only two values: false and True, one byte (8bit), and the default is False.
