For additional information about properties and storage requirements of the numeric types, see Section 11.2, “Numeric Types”, and Section 11.8, “Data Type Storage Requirements”. Display width is unrelated to the range of values a type can ...

These types include the exact numeric data types (INTEGER, SMALLINT, DECIMAL, and NUMERIC), as well as the approximate numeric data types (FLOAT, REAL, and DOUBLE PRECISION). The keyword INT is a synonym for INTEGER, and the keywords DEC and FIXED ...
https://dev.mysql.com/numeric-type-attributes.html
MySQL supports an extension for optionally specifying the display width of integer data types in parentheses following the base keyword for the type. For example, INT(4) specifies an INT with a display width of four digits. This optional display ...

For unique IDs or other values that can be represented as either strings or numbers, prefer numeric columns to string columns. Since large numeric values can be stored in fewer bytes than the corresponding strings, it is faster and takes less ...

(The BIT_AND(), BIT_OR(), and BIT_XOR() aggregate functions are described in Section 12.20.1, “Aggregate (GROUP BY) Function Descriptions”.) Prior to MySQL 8.0, bit functions and operators required BIGINT (64-bit integer) arguments and returned ...

The scope of precision math for exact-value operations includes the exact-value data types (integer and DECIMAL types) and exact-value numeric literals. Approximate-value data types and numeric literals are handled as floating-point numbers.
https://dev.mysql.com/fixed-point-types.html
The DECIMAL and NUMERIC types store exact numeric data values. These types are used when it is important to preserve exact precision, for example with monetary data. In MySQL, NUMERIC is implemented as DECIMAL, so the following remarks about ...

The [ndbd] and [ndbd default] sections are used to configure the behavior of the cluster's data nodes. [ndbd] and [ndbd default] are always used as the section names whether you are using ndbd or ndbmtd binaries for the data node processes. There ...
https://dev.mysql.com/number-literals.html
Number literals include exact-value (integer and DECIMAL) literals and approximate-value (floating-point) literals. Numbers may be preceded by - or + to indicate a negative or positive value, respectively. Numbers represented in scientific notation ...
