C language stipulates that single-precision floating point types occupy 4 bytes in memory, the precision is 7 bits, and the value range is :3.4*10^-38 ~3.4*10^38 or -(3.4*10^-38 ~3.4*10^38)

You can define single-precision floating-point variables, such as float a; that is, define A single-precision floating-point variable a. Related types: double represents a double-precision floating point number.

Floating point numbers are expressed in exponential form in the machine and are decomposed into four parts: number sign, mantissa, exponent sign, and exponent.

The number symbol occupies 1 binary digit and represents the positive or negative number.

The exponent sign occupies 1 binary digit, indicating the positive or negative of the exponent.

The mantissa represents the valid digits of the floating point number, 0.xxxxxxx, but the leading 0 and dot are not stored.

The exponent stores the significant digits of the exponent.
