MySQL numeric data types can be roughly divided into two categories: one is an integer, and the other is a floating point or decimal. Many different subtypes are available for each of these classes. Each subtype supports data of different sizes. MySQL allows us to specify whether the values in the value field are positive or negative or fill with zero. MySQL Data Type-detailed description of decimal The table lists various numeric types, their permitted ranges, and occupied memory space.

The Qianyi "Dragon ice five generations" 1U chassis adopts an innovative integrated design concept of "Chassis + radiator, A passive heat sink with a large heat dissipation area called "qianniu" is directly cooled by a powerful fan in the chassis, which greatly improves the air volume and heat sink area of the CPU cooling fan, it has produced epoch heat dissipation results. In addition, a black heat radiation and efficiency coating is sprayed on the surface of the Qianyi ice overlord heat sink.
