The FLOAT and DOUBLE types represent approximate numeric data values. For FLOAT, the SQL standard permits an optional specification of the precision (but not the range of the exponent) in bits following the keyword FLOAT in parentheses, that is, ...

Floating-point numbers sometimes cause confusion because they are approximate and not stored as exact values. A floating-point value as written in an SQL statement may not be the same as the value represented internally. Attempts to treat ...For ...

For floating-point and fixed-point data types, M is the total number of digits that can be stored. As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support ... For integer data types, M indicates the minimum display ...

The arguments are compared as decimal values if the other argument is a decimal or integer value, or as floating-point values if the other argument is a floating-point value. In all other cases, the arguments are compared as floating-point ... When ...

Because conversions between decimal and binary representations of them may be approximate, comparisons involving floating-point values are inexact. This is true for operations that use floating-point values explicitly, or that use values that are ...

FLOAT[(p)] If the precision p is not specified, produces a result of type FLOAT. If p is provided and 0 <= < p <= 24, the result is of type FLOAT. This is actually FLOAT if the REAL_AS_FLOAT SQL mode is enabled; otherwise the result is of type ...

The functions CAST() and CONVERT() now support conversions to types DOUBLE, FLOAT, and REAL. Such implicit casts are now performed between temporal types (DATE, DATETIME, TIMESTAMP, TIME) and numeric types (SMALLINT, TINYINT, MEDIUMINT, INT/INTEGER, ... This section summarizes what has been added to, deprecated in, and removed from MySQL ...

Number literals include exact-value (integer and DECIMAL) literals and approximate-value (floating-point) literals. For example, 2.34 is an exact-value (fixed-point) number, whereas 2.34E0 is an approximate-value (floating-point) number. The FLOAT ...Numbers may be preceded by - or + to indicate a negative or positive value, ...
