Often asked: How many digits can an int hold?

What is the limit of INT?

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 many digits can an INT hold Java?

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.

How many digits can a long long hold?

Longer integers: long

The long data type stores integers like int, but gives a wider range of values at the cost of taking more memory. Long stores at least 32 bits, giving it a range of -2,147,483,648 to 2,147,483,647. Alternatively, use unsigned long for a range of 0 to 4,294,967,295.

What are the limits of int datatype?

In this article

Type Name Bytes Range of Values
int 4 -2,147,483,648 to 2,147,483,647
unsigned int 4 0 to 4,294,967,295
__int8 1 -128 to 127
unsigned __int8 1 0 to 255

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 limit of int in C?

Integer Types

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
short 2 bytes -32,768 to 32,767
unsigned short 2 bytes 0 to 65,535

Is Long bigger than double Java?

Beyond that, DOUBLE stores decimal values with a higher precision (24-53 digits) than a FLOAT type. LONG is used when a wider range than INT is needed.

What is bigger than int in 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).

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.

Why int is 2 or 4 bytes?

So the reason why you are seeing an int as 4 bytes (32 bits), is because the code is compiled to be executed efficiently by a 32-bit CPU. If the same code were compiled for a 16-bit CPU the int may be 16 bits, and on a 64-bit CPU it may be 64 bits.

What is the smallest INT available on your system?

A short int which has two bytes of memory, has a minimum value range of -32,768 and a maximum value range of 32,767. An unsigned short int, unsigned meaning having no negative sign (-), has a minimum range of 0 and a maximum range of 65,535.

What is the biggest number in C++?

So what is the biggest number usable by c++ language? Ignoring all the arbitrary precision stuff, the largest unsigned integer C++ can handle is 18,446,744,073,709,551,616, which is a long long int.

What is bigger than long long int?

A double or long double can typically represent numbers with larger magnitudes than a long long, but often with less precision (e.g., frequently 53 bits vs., 63 bits for a long long). If you want a larger integer type, you’ll typically want to use a library.

How do you use long int?

long int

  1. A long int typically uses twice as many bits as a regular int, allowing it to hold much larger numbers.
  2. printf and scanf replace %d or %i with %ld or %li to indicate the use of a long int.
  3. long int may also be specified as just long.

How large is an int C++?

Integer: Keyword used for integer data types is int. Integers typically requires 4 bytes of memory space and ranges from -2147483648 to 2147483647. Character: Character data type is used for storing characters. Keyword used for character data type is char.
