cobol numeric data types

value can range from 84 to 127. For example:CREATE TABLE Test(Name Number (5))Use the precision 5来 to define a positive number (such as 12345).CREATE TABLE Test(Name Number (5,2))Use Precision 5 and range to define a number. Numeric values that conform to this data type, such as 123.45 and 12.346, LONGA LONG column stores a variable-length string that can store up to 2GB of

Numeric type Numeric types are roughly divided into two broad categories: One is an integer, the other is a floating-point number or a decimal. An int type is commonly used for integer types, allowing the range to be between ( -2147483648,2147483648). Floating-point or decimal common

program execution efficiency, the underlying data structure of each object can be implemented in more than one way. Encoding represents the encoding used at the bottom of the object. The following is an introduction to each of the underlying data structure implementations, and then to the underlying structure of each object type and analysis of their relationships. Redis Object underlying

PLSQL data types and operators PL/SQL data types and operators Scalar Data Type Scalar data types have no internal components. They can be divided into the following four categories:

abstract data types are a theoretical tool for describing data structures. Before we introduce the abstract data types, let's introduce aBasic concepts of the following data types. A

undefined.3.boolean typeA Boolean type has only two values: True and False. These two values are not the same as numeric values, so true is not necessarily equal to 1,false or not necessarily equal to 0.The literal value of Boolean literals True and false is case-sensitive. Like true and False are not Boolean values, but identifiers.Although the Boolean type has only two values, other types of values have

that is stored entirely according to its input. SQLite's storage classes are slightly more common than data types. An integer storage class, for example, contains 6 different lengths of integral data types.SQLite Affinity (Affinity) typeSQLite supports the affinity type concept for columns. Any column can still store any type of

collection of up to 64K strings enumeration, which can hold only one of the listed values or null for that type of column SET accepts 0 or more strings of a predefined set consisting of up to 64K strings The value in the specified column must come from a specified value in a specific collection, for example: set (' C ', ' H ', ' P ', ' f ', ' s ', ' j ', ' A ', ' B ') Dede's homepage recommends popular settings Note: Regardless of the string

Below I will introduce some experiences in development to you. We know that the
