Unlike the integer type, the float type uses a fixed number of bytes. Technically, Python uses 64 bits as follows: 1 bit for sign (positive or negative) 11 bits for exponent 1.5e-5 1.5 x 10-5 (exponent is -5) the range is [-1022, 1023]. 52 bits for significant digits
WebInstead, Python uses a variable number of bits to store integers. For example, 8 bits, 16 bits, 32 bits, 64 bits, 128 bits, and so on. The maximum integer number that Python can represent depends on the memory available. Also, integers are objects. Python needs an extra fixed number of bytes as an overhead for each integer. Webbit_length() 是 Python 中 int 类型的一个方法，用于返回该整数的二进制表示中所需的位数。例如，(10).bit_length() 返回 4，因为 10 的二进制表示为 1010，需要 4 位来表示。

Common bit-lengths of binary numbers include bits, nibbles, and bytes (hungry yet?). Each 1 or 0 in a binary number is called a bit. From there, a group of 4 bits is called a nibble, and 8-bits makes a byte. portal object storage
