A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.
The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with. This allows great flexibility: for example, all types can be 64-bit.
Originally designed as an 8-bit file system, the maximum number of clusters must increase as disk drive capacity increases, and so the number of bits used to identify each cluster has grown. The successive major variants of the FAT format are named after the number of table element bits: 12 ( FAT12 ), 16 ( FAT16 ), and 32 ( FAT32 ).
In the 64-bit version, all Windows applications and components are 64-bit, although many also have their 32-bit versions included for compatibility with plug-ins. [citation needed] 2007 Apple releases Mac OS X 10.5 "Leopard", which fully supports 64-bit applications on machines with PowerPC 970 or EM64T processors. [citation needed] 2009
Windows 10 can run on both 32-bit and 64-bit processor architectures. If you have a computer with a 32-bit setup, you can upgrade to the 64-bit version without acquiring a new license.
All 32-bit editions of Windows 10, including Home and Pro, support up to 4 GB. [291] 64-bit editions of Windows 10 Education and Pro support up to 2 TB, 64-bit editions of Windows 10 Pro for Workstations and Enterprise support up to 6 TB, while the 64-bit edition of Windows 10 Home is limited to 128 GB.

A floating-point variable can represent a wider range of numbers than a fixed-point variable of the same bit width at the cost of precision. A signed 32-bit integer variable has a maximum value of 2 31 − 1 = 2,147,483,647, whereas an IEEE 754 32-bit base-2 floating-point variable has a maximum value of (2 − 2 −23) × 2 127 ≈ 3.4028235 ...
