# What is the largest integer data type?

Contents

In ISO C99 long long is at least 64bit which is the largest standard integer data type. It also comes as unsigned long long . Apparently your compiler might provide larger types wich defined by intmax_t and uintmax_t .

## 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 the largest int?

Limits on Integer Constants

Constant Meaning Value
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
LONG_MAX Maximum value for a variable of type long . 2147483647

## What datatype is used for very large numbers?

The largest integer number that a long type can represent is 9223372036854775807. If we deal with even larger numbers, we have to use the java. math.

Integers.

Type Size Range
long 64 bits -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807

## What is the size of integer data type?

Data Types and Sizes

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

## Is float bigger than int?

The exponent allows type float to represent a larger range than that of type int . However, the 23-bit mantissa means that float supports exact representation only of integers whose representation fits within 23 bits; float supports only approximate representation of integers outside that range.

## What is a void data type?

The void data type, similar to the Nothing data type described earlier, is the data type for the result of a function that returns normally, but does not provide a result value to its caller.

## What is the 2 bit integer limit?

As the table shows, if a storage type is n-bits wide, the minimum value that can be correctly stored is -(2^(n-1)) and the maximum value is 2^(n-1) – 1.

Integer Data Storage Types.

Size Minimum Value Maximum Value
32-bits -(2^31) = -2,147,483,648 2^31 – 1 = 2,147,483,647

## Which is the smallest integer?

The smallest integer is zero.

## 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. It is important to note that a computer memory location merely stores a binary pattern.

## Is Long bigger than double Java?

Closed 1 year ago. Looking at Java (but probably similar or the same in other languages), a long and a double both use 8 bytes to store a value. A double uses 8 bytes to store double-precision, floating-point numbers from -1.7E308 to 1.7E308 with up to 16 significant digits.

## What is big integer in C++?

We can use big integer datatype. We can use different datatypes like int128_t, int256_t, int1024_t etc. By using this we can get precision up to 1024 easily. At first we are multiplying two huge number using boost library.

## How many digits can a long hold in Java?

A long can store a value from -9223372036854775808 to 9223372036854775807 . A primitive long or its java. lang. Long wrapper can also store ten digits.

## 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.

## 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.

## What are the 5 data types?

The data types to know are:

• String (or str or text). Used for a combination of any characters that appear on a keyboard, such as letters, numbers and symbols.
• Character (or char). Used for single letters.
• Integer (or int). Used for whole numbers.
• Float (or Real). …
• Boolean (or bool).
