# What Is A Long Variable?

## What is the difference between int and long?

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..

## What are the 5 data types?

Common data types include:Integer.Floating-point number.Character.String.Boolean.

## How do you convert long to int?

Java Long to int Examplepublic class LongToIntExample2{public static void main(String args[]){Long l= new Long(10);int i=l.intValue();System.out.println(i);}}

## Should I use double or float?

Float and double Double is more precise than float and can store 64 bits, double of the number of bits float can store. Double is more precise and for storing large numbers, we prefer double over float. For example, to store the annual salary of the CEO of a company, double will be a more accurate choice.

## What is the long data type?

Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer. Because the long data type is signed, the possible integers range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, including 0. …

## What is a long variable in Java?

long: The long data type is a 64-bit two’s complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.

## What are the variables in VBA?

Summary:Variables are specific values that are stored in a computer memory or storage system.You can use “Dim” keyword in syntax to declare variable explicitly.VBA data types can be segregated into two types. … In VBA, if the data type is not specified. … Constant is like a variable, but you cannot modify it.

## Is double bigger than float?

A double is 64 and single precision (float) is 32 bits. The double has a bigger mantissa (the integer bits of the real number).

## 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.

## What is difference between double and long?

The main difference between long and double in Java is that long is a data type that stores 64 bit two’s complement integer while double is a data type that stores double prevision 64 bit IEEE 754 floating point. In brief, long is an integral type whereas double is a floating point type.

## Do you need to declare variables in VBA?

You don’t need to declare variables to make the VBA code work.

## How do you use variables in VBA?

To declare a variable, type Dim, the variable name, and the variable type… somewhat like this… If you don’t specify the type of variable, as shown in the first example at the top of this post, VBA declares the variable as a Variant type. A Variant can accept any type of variable.

## 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.

## Why is a character 1 byte?

char is 1 byte in C because it is specified so in standards. … the (binary) representation of a char (in standard character set) can fit into 1 byte. At the time of the primary development of C , the most commonly available standards were ASCII and EBCDIC which needed 7 and 8 bit encoding, respectively.

## What is long variable in VBA?

VBA Data Types: Long. Introduction. A long integer is a number that can be used for a variable involving greater numbers than integers. To declare a variable that would hold such a large number, use the Long data type.

## What is the size of Long variable?

## 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.

## 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.
