Get the number of bits of a big number
WebAug 2, 2024 · The mantissa represents a number between 1.0 and 2.0. Since the high-order bit of the mantissa is always 1, it is not stored in the number. This representation gives a range of approximately 3.4E-38 to 3.4E+38 for type float. You can declare variables as float or double, depending on the needs of your application.

WebThe easiest way to do this is to subtract the netmask length from 32 (number of bits in an IPv4 address). This gives you the number of host bits in the address. At that point... Maximum Number of hosts = 2** (32 - netmask_length) - 2 The reason we subtract 2 above is because the all-ones and all-zeros host numbers are reserved.
