# What is the biggest number an int can hold in Java?

Contents

The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Why those numbers? Integers in Java are represented in 2’s complement binary and each integer gets 32 bits of space.

## What is the biggest number an int can hold?

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 long max value in Java?

Summary of Data Types

Primitive Type Size Maximum Value
byte 8-bit +127
short 16-bit +215-1 (32,767)
int 32-bit +231-1 (2,147,483,647)
long 64-bit +263-1 (9,223,372,036,854,775,807)

## How many digits can Int hold?

The INTEGER data type stores whole numbers that range from -2,147,483,647 to 2,147,483,647 for 9 or 10 digits of precision. The number 2,147,483,648 is a reserved value and cannot be used. The INTEGER value is stored as a signed binary integer and is typically used to store counts, quantities, and so on.

## What is bigger than int in Java?

short 2 bytes -32,768 to 32,767. int 4 bytes -2,147,483,648 to 2,147,483,647. long 8 bytes -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.

## What is the highest number?

Googol. It is a large number, unimaginably large. It is easy to write in exponential format: 10100, an extremely compact method, to easily represent the largest numbers (and also the smallest numbers).

## 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

## What is character max value?

char: The char data type is a single 16-bit Unicode character. It has a minimum value of ‘u0000’ (or 0) and a maximum value of ‘uffff’ (or 65,535 inclusive).

## What is Max Long?

In computer science, the term max long may also refer to the maximum value that can be represented by a long integer data type.

## What is byte [] in Java?

The byte data type in Java is a signed integer based on the two’s complement 8-bit mechanism. It is different from the int data type that uses 4 bytes (i.e., 32-bit to store a number). The values that can be stored in a single byte are -128 to 127. byte data types are primitive.

## What are the 4 data types?

Common data types include:

• Integer.
• Floating-point number.
• Character.
• String.
• Boolean.

## 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 the same as int?

The basic difference between the type int and long is of their width where int is 32 bit, and long is 64 bits. … In Java, the range of type int is from –2,147,483,648 to 2,147,483,647 whereas, the range of type long is from –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 which is very much greater than type int.

## Is Long bigger than int Java?

When we want to store a value bigger than int range, we should use long type. With long, we can store up to a 19 digit number. (in C, long is a data modifier but in Java long is a data type). When using a constant bigger than int range, we should suffix it with ‘l’ or ‘L’ to indicate it to be a long value.

## What is the biggest data type in Java?

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.

Integers.

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

## Is Long bigger than int?

On many (but not all) C and C++ implementations, a long is larger than an int. … You will find some platforms where int is 32 bits, long is 64 bits, and long long is 128 bits, but it seems very common for sizeof (long) to be 4.
