# Best answer: What is the lowest data that can be kept in an integer?

Contents

Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,294,967,295 (232 – 1) can be stored.

## What is storage size for integer data type?

Numeric Type Storage Requirements

Data Type Storage Required
SMALLINT 2 bytes
MEDIUMINT 3 bytes
INT , INTEGER 4 bytes
BIGINT 8 bytes

## What is the minimum and maximum value an integer variable can store?

Limits on Integer Constants

Constant Meaning Value
INT_MIN Minimum value for a variable of type int . -2147483648
INT_MAX Maximum value for a variable of type int . 2147483647
UINT_MAX Maximum value for a variable of type unsigned int . 4294967295 (0xffffffff)
LONG_MIN Minimum value for a variable of type long . -2147483648

## What is the minimum size in bits for int?

int: By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -231 and a maximum value of 231-1. In Java SE 8 and later, you can use the int data type to represent an unsigned 32-bit integer, which has a minimum value of 0 and a maximum value of 232-1.

## How many bits are in an integer?

In ‘C’, an unsigned integer is usually 16 bits.

Decimal 4 bit 8 bit
3 0011 0000 0011
-3 1101 1111 1101
7 0111 0000 0111
-5 1011 1111 1011

## What is the size of integer?

Data Types and Sizes

Type Name 32–bit Size 64–bit Size
char 1 byte 1 byte
short 2 bytes 2 bytes
int 4 bytes 4 bytes
long 4 bytes 8 bytes

## What is the size bytes of data type void?

The size of void pointer varies system to system. If the system is 16-bit, size of void pointer is 2 bytes. If the system is 32-bit, size of void pointer is 4 bytes. If the system is 64-bit, size of void pointer is 8 bytes.

## Which data type can hold the largest integer?

int: Holds 32-bit signed integers. The smallest possible value of an int variable is -2,147,483,648; the largest possible value is 2,147,483,647.

## What is maximum integer value?

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, and the maximum possible score, money, etc.

## What is the 64 bit integer limit?

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).

## Why int is 2 or 4 bytes?

The size of an int is really compiler dependent. Back in the day, when processors were 16 bit, an int was 2 bytes. Nowadays, it’s most often 4 bytes on a 32-bit as well as 64-bit systems. Still, using sizeof(int) is the best way to get the size of an integer for the specific system the program is executed on.

## What is the 8-bit integer limit?

An 8-bit unsigned integer has a range of 0 to 255, while an 8-bit signed integer has a range of -128 to 127 – both representing 256 distinct numbers.

## What is the 4 bit integer limit?

With 4 bits, it is possible to create 16 different values. All single-digit hexadecimal numbers can be written with four bits.

## What is 32-bit integer?

In computer architecture, 32-bit integers, memory addresses, or other data units are those that are 32 bits (4 octets) wide. Also, 32-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

## Is Long An integer?

An int is a 32-bit integer; a long is a 64-bit integer. … int and long are primitive types, while Integer and Long are objects.

## How many bytes is a word?

A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits). Figure 29-2 shows the byte order of each of the fundamental data types when referenced as operands in memory.
