How many bytes does float occupy?

The float type occupies 4 bytes of memory, representing decimals. The data range is between [-2^128 ~ 2^128] [-3.40E 38 ~ 3.40E 38]; the float data type is used to store single Precision floating point number or double precision floating point number.

The float type occupies 4 bytes of memory, represents a decimal, and the data range is -2^128 ~ 2^128 (-3.40E 38 ~ 3.40E 38) between.

The int type occupies 4 bytes of memory, represents an integer, and the data range is between -2^31~2^31-1(-2147483648~2147483647).

The char type occupies 1 byte of memory, representing characters, and the data range is between -2^7~2^7-1(-128 ~127).

Extended information:

The float data type is used to store single-precision floating-point numbers or double-precision floating-point numbers. Floating point numbers use the IEEE (Institute of Electrical and Electronics Engineers) format. The single-precision value of the floating point type includes four parts: number sign, mantissa, exponent sign, and exponent. Since the high-order bit of the mantissa is always 1, it is not stored as a number.

Float data is expressed in exponential form in the machine. The number symbol occupies 1 binary digit, indicating the positive and negative of the number. The exponent sign occupies 1 binary digit and represents the positive or negative exponent. The mantissa represents the valid digits of the floating point number, 0.xxxxxxx, but the leading 0 and dot are not stored. How many digits the exponent occupies and how many digits the mantissa occupies are determined by the computer system.
