From the storage structure and algorithm, double and float are the same, the difference is only float is 32-bit, double is 64-bit, so double can store higher precision.
Any data in memory is stored in binary (0 or 1) order, each 1 or 0 is called 1 bits, and the X86CPU is 8 bits. For example, the value of a 16-bit (2-byte) Shortint variable is 1000, and its binary expression is 0000001111101000. Because of Intelcpu's architectural reasons, it is stored

storage is not a good way to go, but to integrate, both to be able to store their own storage as the data center of the cloud computing age. This article also explores how traditional commercial storage can be supported by cloud computing. Here we will refine the cloud, just to discuss OpenStack and Hadoop. Of course this is a bit one-sided. But since no one can give the academic definition of cloud computing, our one-sided is not a big mistake.
