Ensuite, Does C have long long?
So, yes, this is the biggest integer type specified by C language standard (C99 version). There is also long double type specified by C99. It’s an extended precision floating point numeric data type long for 80-bits on most popular x86-based platforms and implementations of C language.

Or, Is Long same as int?
The long is a larger data type than int. The difference between int and long is that int is 32 bits in width while long is 64 bits in width.
What is the difference between int and long int?
An int is a 32-bit integer; a long is a 64-bit integer. Which one to use depends on how large the numbers are that you expect to work with. int and long are primitive types, while Integer and Long are objects.
What is an example of long integer?
It helps to break down each word, starting from right to left. An integer is a whole number that does not include a decimal point. Examples include 1, 99, or 234536. « Signed » means the number can be either positive or negative, since it may be preceded by a minus (-) symbol.
How do you convert int to long?
Java int can be converted to long in two simple ways:
- Using a simple assignment. This is known as implicit type casting or type promotion, the compiler automatically converts smaller data types to larger data types.
- Using valueOf() method of the Long wrapper class in java which converts int to long.
What is long integer in Java?
The long is a numeric data type in Java. This is also the primitive type. The long type takes 64 bits of memory. The maximum value that a long type variable can store is 9,223,372,036,854,775,807L. The minimum value is -9,223,372,036,854,775,808L.
What is above long long?
unsigned long long is larger than long long. long long = 9223372036854775807. unsigned long long = 18446744073709551615.
Can we use long long in Java?
Nope, there is not. You’ll have to use the primitive long data type and deal with signedness issues, or use a class such as BigInteger .
What is the range of unsigned long long int?

Why are long and int the same?
« a long in C/C++ is the same length as an int. » Not always. The C++ standard specifies that an int be the « natural » size for the processor, which may not always be as big as a long . The standard also guarantees that a long is at least as long as an int , so the fact that they are equal sizes are not always guaranteed.
Why do we use long int?
Sometimes, the range of long is the same as int (32-bit systems; 64-bit Windows); then the main reason for using long or int is to match the interface to a particular API (because the types are still distinct, even if they support the same range).
What is a long long?
LongLong (LongLong integer) variables are stored as signed 64-bit (8-byte) numbers ranging in value from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. The type-declaration character for LongLong is the caret (^). LongLong is a valid declared type only on 64-bit platforms.
How do you use long int?
long int
- A long int typically uses twice as many bits as a regular int, allowing it to hold much larger numbers. …
- printf and scanf replace %d or %i with %ld or %li to indicate the use of a long int.
- long int may also be specified as just long.
How do I print long integers?
You must use %ld to print a long int , and %lld to print a long long int . Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you’re using).
What is long number?
A Long Code or Long Number is a standard-length (10-digits) virtual phone number that can be used by businesses to send and receive SMS and MMS messages, or to make and receive voice calls. They are cheaper to use than short codes.
How many digits is a long?
Common integral data types
| Bits | Name | Decimal digits |
|---|---|---|
| 32 | word, long, doubleword, longword, int, i32, u32 | 9.63 |
| 64 | word, doubleword, longword, long long, quad, quadword, qword, int64, i64, u64 | 18.96 |
| 19.27 |
Can an int be a long?
Since int is smaller data type than long, it can be converted to long with a simple assignment. This is known as implicit type casting or type promotion, compiler automatically converts smaller data type to larger data type.
How do you convert int to long in Python?
Type int(x) to convert x to a plain integer. Type long(x) to convert x to a long integer. Type float(x) to convert x to a floating-point number.
What is long valueOf in Java?
valueOf() is a built-in method in Java of lang class that returns a Long object holding the value extracted from a specified String S when parsed with the radix that is given in the second argument.
