       For storing numeric data, MySQL provides integer data  types, floating-point types that store approximate-value (real) numbers, a fixed-point type that stores exact-value (real) numbers, and a BIT type for bit-field  values.  When numeric data type is chosen, consider the following factors:   •   The range of values the data type represents   •   The amount of storage space that column values require   •   The column precision and scale for floating-point and fixed-point values   Precision and scale are terms that apply to floating-point and fixed-point values, which can have both an  integer part and a fractional part. Precision is the number of significant digits. Scale is the number of digits  to the right of the decimal point.  Integer Data Type  The integer data types are summarized in the following table, which indicates the amount of storage per  valu...
