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.
How big can an int be?
Integer Types
Type | Storage size | Value range |
---|---|---|
unsigned char | 1 byte | 0 to 255 |
signed char | 1 byte | -128 to 127 |
int | 2 or 4 bytes | -32,768 to 32,767 or -2,147,483,648 to 2,147,483,647 |
unsigned int | 2 or 4 bytes | 0 to 65,535 or 0 to 4,294,967,295 |
What is the largest 64 bit integer?
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).
How big can Java int be?
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.
What is the largest data type?
In ISO C99 long long is at least 64bit which is the largest standard integer data type. It also comes as unsigned long long .
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.
How do you convert long to int?
Let’s see the simple code to convert Long to int in java.
- public class LongToIntExample2{
- public static void main(String args[]){
- Long l= new Long(10);
- int i=l.intValue();
- System.out.println(i);
- }}
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 the 64 bit limit?
64 bit computing
Modern 64-bit processors such as designs from ARM, Intel or AMD are typically limited to supporting fewer than 64 bits for RAM addresses. They commonly implement from 40 to 52 physical address bits (supporting from 1 TB to 4 PB of RAM).
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 does float a 35 0 return mean?
10) What does the expression float a = 35 / 0 return? Explanation: In Java, whenever we divide any number (double, float, and long except integer) by zero, it results in infinity. … But on dividing an integer by zero, it throws a runtime exception, i.e., java.lang.ArithmeticException.

What data type is a person’s name?
Person name is a standard XDM data type that describes the full name of a person. As conventions for name structures differ widely across languages and cultures, names should always be modeled using this datatype.
Is int a data type?
Int. The int data type can store whole numbers from -2147483648 to 2147483647. In general, and in our tutorial, the int data type is the preferred data type when we create variables with a numeric value.
