MySQL中Decimal类型和Float Double的区别(详解)
MySQL float is a data type used to store floating-point numbers with a precision of up to 24 digits. It is commonly used to store decimal numbers that require a high degree of precision, such as financial data or scientific measurements. Float values can be positive or negative and can include decimal points. The maximum value that can be stored in a MySQL float is approximately 3.4 x 10^38, while the smallest positive value is approximately 1.18 x 10^-38. Float values in MySQL can be declared using the FLOAT or DOUBLE keyword, with DOUBLE providing a higher degree of precision than FLOAT.
