Can we use long in C?

The maximum possible integer input can be taken in C using long long int. It has a range of −9,223,372,036,854,775,807 to +9,223,372,036,854,775,807. If you only deal with positive numbers then unsigned long long can be used which has a range of 0 to 18,446,744,073,709,551,615.

How many digits is a long?

Type Name	Bytes	Range of Values
long long	8	-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
unsigned long long	8	0 to 18,446,744,073,709,551,615
enum	varies
float	4	3.4E +/- 38 (7 digits)

Can integers be decimals? Key idea: Like whole numbers, integers don't include fractions or decimals.

What is the integer symbol?

The letter (Z) is the symbol used to represent integers. An integer can be 0, a positive number to infinity, or a negative number to negative infinity. Is long an int? long and long int are identical. So are long long and long long int . In both cases, the int is optional. As to the difference between the two sets, the C++ standard mandates minimum ranges for each, and that long long is at least as wide as long .

Should I use long or int?

Long is the Object form of long , and Integer is the object form of int . The long uses 64 bits. The int uses 32 bits, and so can only hold numbers up to ±2 billion (-2³¹ to +2³¹-1). You should use long and int , except where you need to make use of methods inherited from Object , such as hashcode . What is an example of long integer? Therefore, if a variable or constant may potentially store a number larger than 2,147,483,647 (2³¹ ÷ 2), it should be defined as a long instead of an int. NOTE: In standard C, a long integer may be limited to a 32-bit value ranging from -2,147,483,648 to 2,147,483,647.

Is long long double C++?

Data Type	Size (in bytes)	Range
short int	2	-32,768 to 32,767
long double	12
wchar_t	2 or 4	1 wide character

Is double better than long? If you are storing integers, use Long . Your statement that "Advantage of Using Double is that it gives a more wider range for storing Whole Numbers" is incorrect. Both are 64 bits long, but double has to use some bits for the exponent, leaving fewer bits to represent the magnitude.

What is larger double or long?

A simple answer is that double is only accurate to 15-16 total digits, as opposed to long which (as an integer type) has an absolute accuracy within an explicit digit limit, in this case 19 digits.
