IEEE Binary Floating-point Arithmetic Standard (IEEE 754) is the most widely used floating-point arithmetic standard, which stipulates four ways to represent floating-point values: single precision (32 bits), double precision (64 bits), extended single precision (over 43 bits, rarely used) and extended double precision (over 79 bits, usually 80 bits).

floating-point number

In C language, floating-point numbers are stored in two ways, namely, float and double, and of course, long double. These floating-point types contain different lengths and, of course, different storage accuracy.

Plastic surgery, such as int, short, char and so on, are all stored in memory? Supplement? Make a statement. Floating-point numbers are not represented by complement in memory. Are floating-point numbers stored in memory used? IEEE？ The encoded representation of, that is, using the. Symbol, index? And then what? Mantissa? In the form of.
