# What is LongLong data type?

## What is LongLong data type?

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.

### What are the types of data type?

data type

Data Type | Used for | Example |
---|---|---|

Integer | Whole numbers | 7, 12, 999 |

Float (floating point) | Number with a decimal point | 3.15, 9.06, 00.13 |

Character | Encoding text numerically | 97 (in ASCII, 97 is a lower case ‘a’) |

Boolean | Representing logical values | TRUE, FALSE |

**What is type long long in C?**

According to C99 standard, long long is an integer type which is at least 64-bit wide. There are two integer 64-bit types specified: long long int and unsigned long long int. So, yes, this is the biggest integer type specified by C language standard (C99 version).

**Is long 32-bit or 64-bit?**

Windows: long and int remain 32-bit in length, and special new data types are defined for 64-bit integers.

## How big is a longlong?

Executive summary: it’s 64 bits, or larger. unsigned long long is the same as unsigned long long int . Its size is platform-dependent, but guaranteed by the C standard (ISO C99) to be at least 64 bits.

### What is float data type?

The FLOAT data type stores double-precision floating-point numbers with up to 17 significant digits. FLOAT corresponds to IEEE 4-byte floating-point, and to the double data type in C. The range of values for the FLOAT data type is the same as the range of the C double data type on your computer.

**What are the 5 data types?**

Common data types include:

- Integer.
- Floating-point number.
- Character.
- String.
- Boolean.

**How many data types are there?**

Most modern computer languages recognize five basic categories of data types: Integral, Floating Point, Character, Character String, and composite types, with various specific subtypes defined within each broad category.

## Is long 64-bit C?

long , ptr , and off_t are all 64 bits (8 bytes) in size. The 32-bit data model for z/OSĀ® XL C/C++ compilers is ILP32 plus long long.

### What is a C++ long?

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.

**How many bytes is a longlong?**

8 bytes

The size of the long type is 8 bytes (64 bits).

**What is the meaning of uint8_t?**

Unsigned Integers of 8 bits. A uint8 data type contains all whole numbers from 0 to 255. As with all unsigned numbers, the values must be non-negative. Uint8’s are mostly used in graphics (colors are always non-negative).
