How many bytes do you need to store 64 bits of data?

In principle, a 64-bit microprocessor can address 16 EiB (16 × 10246 = 264 = 18,446,744,073,709,551,616 bytes, or about 18.4 exabytes) of memory.

How many bytes is a 64 bit integer?

The names of the integer types and their sizes in each of the two data models are shown in the following table. Integers are always represented in twos-complement form in the native byte-encoding order of your system….Data Types and Sizes.

Type Name 32–bit Size 64–bit Size
int 4 bytes 4 bytes
long 4 bytes 8 bytes
long long 8 bytes 8 bytes

How many numbers can be stored in 64 bits?

As a recap, remember that the maximum number stored in a 64 bit register / variable is 2^64 – 1 = 18446744073709551615 (a 20 digit number).

What is a 64-bit number?

A 64-bit signed integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). A 64-bit unsigned integer. It has a minimum value of 0 and a maximum value of (2^64)-1 (inclusive).

What does 32bit 64bit mean?

The terms 32-bit and 64-bit refer to the way a computer’s processor (also called a CPU), handles information. The 64-bit version of Windows handles large amounts of random access memory (RAM) more effectively than a 32-bit system.

How do I get 64-bit?
