floating point numbers
1. What are floating point numbers
In the process of computer system development, several methods have been proposed to express real numbers. Typically, for
Storage Method of floating point and floating point in memory, floating point
First, let's talk about how to convert decimal places to binary decimal places. The computer doesn't even know the decimal data. He only knows 0 and 1. So, decimal decimal
This paper is derived from quantization, data type, overflow and underflow, and the floating-point number is considered as a quantization method of real field, and the difference between floating-point number, especially irregular floating-point
Use symbolic constants in header file Cfloat to learn the range of table numbers for floating-point type dataCfloat header file contains the length limit of the floating-point number of the systemThe symbolic constants in the header file Climits are
Although almost every processor andProgramming LanguageAll support floating point operations, but mostProgramStaff seldom pay attention to it. This is easy to understand-most of us seldom need non-integer types. In addition to scientific computing

MySQL floating point type, mysql floating point type
MySQL floating-point and fixed-point types can be expressed by the type name plus (M, D). M indicates the total length of the value, and D indicates the length after the decimal point, M and D are
First, let's look at a piece of code (in VC, in C ++ ):
int a = 2; int b = 3; int c = 6; if(1.0 / a + 1.0 / 3 + 1.0 / c >= 1.0) cout
