What is the maximum value of a 16-bit number?
65,535
A 16-bit register can store a positive number between 0 and 216 − 1, that is, 65,535. Thus a 16-bit word can be used for positive numbers in the range 0 to 65,535.
How big is a 16-bit integer?
Integer, 16 Bit: Signed Integers ranging from -32768 to +32767. Integer, 16 bit data type is used for numerical tags where variables have the potential for negative or positive values. Integer, 16 Bit Unsigned: Unsigned whole or natural numbers ranging from 0 to +65535.
What is the 15 bit integer limit?
Integer Data Storage Types
| Size | Minimum Value | Maximum Value |
|---|---|---|
| 16-bits | -(2^15) = 32,767 | 2^15 – 1 = 32,767 |
| 32-bits | -(2^31) = -2,147,483,648 | 2^31 – 1 = 2,147,483,647 |
| 64-bits | -(2^63) ~= -(9 x 10^19) | 2^63 – 1 ~= 9 x 10^19 |
| 128-bits | -(2^127) ~= -(1.7 x 10^39) | 2^127 – 1 ~= 1.7 x 10^39 |
Are ints 16 bits?
The size of a signed int or unsigned int item is the standard size of an integer on a particular machine. For example, in 16-bit operating systems, the int type is usually 16 bits, or 2 bytes. In 32-bit operating systems, the int type is usually 32 bits, or 4 bytes.

How many bits are in an integer?
In ‘C’, a signed integer is usually 16 bits.
What is a bit integer?
Integers are commonly represented in a computer as a group of binary digits (bits). The size of the grouping varies so the set of integer sizes available varies between different types of computers. Computer hardware nearly always provides a way to represent a processor register or memory address as an integer.
What is the usual meaning of 16-bit in the phrase 16-bit computer?
In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets) wide. Also, 16-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. A 16-bit register can store 216 different values.
What is 16 bits called?
BYTE – 8 bits, unsigned. WORD – 16 bits, unsigned. DWORD – 32 bits, unsigned.
What is INT_MAX and Int_min?
INT_MAX is a macro that specifies that an integer variable cannot store any value beyond this limit. INT_MIN specifies that an integer variable cannot store any value below this limit. Values of INT_MAX and INT_MIN may vary from compiler to compiler. Value of INT_MAX is +2147483647. Value of INT_MIN is -2147483648.
What is the bit integer limit?
The number 2,147,483,647 (or hexadecimal 7FFFFFFF16) is the maximum positive value for a 32-bit signed binary integer in computing. It is therefore the maximum value for variables declared as integers (e.g., as int ) in many programming languages.
What is the maximum integer for 16 bit?
A 16-bit integer can store 2 16 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.
What is the largest 16 bit integer?
The Modbus message uses a 16 bit word to identify the point number to be read/written. The largest number that can fit in 16 bits is 65535 and hence the highest point number that can be read is point 65535.
What is the range of a 16 bit signed integer?
The signed range of integer values that can be stored in 16 bits is −32,768 (−1 × 2 15) through 32,767 (2 15 − 1); the unsigned range is 0 through 65,535 (2 16 − 1). Since 2 16 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory. Sep 2 2019
What is 32 bit integer limit?
The number 2,147,483,647 (or hexadecimal 7FFF,FFFF 16) is the maximum positive value for a 32-bit signed binary integer in computing.
