What is cardinal in Delphi?
What is cardinal in Delphi?
The Cardinal type is an unsigned integer subrange whose size is the natural size of an integer. In Delphi 5, the size is 32 bits, but in future versions of Delphi, it might be larger. Use LongWord for an unsigned integer type that must be 32 bits, regardless of the natural size of an integer.
What is the size of LongWord?
A longsword (also spelled as long sword or long-sword) is a type of European sword characterized as having a cruciform hilt with a grip for two-handed use (around 16 to 28 cm or 6 to 11 in), a straight double-edged blade of around 85 to 110 cm (33 to 43 in), and weighing approximately 1 to 1.5 kg (2 lb 3 oz to 3 lb 5 …
What is dword in Delphi?
DWORD is a 4-byte unsigned integer.
How big is an integer in Delphi?
Platform-Independent Integer Types
| Type | Range | Format |
|---|---|---|
| Integer | -2147483648..2147483647 | Signed 32-bit |
| Int64 | -9223372036854775808..9223372036854775807 (-263..263-1) | Signed 64-bit |
| Byte | 0..255 | Unsigned 8-bit |
| Word | 0..65535 | Unsigned 16-bit |
Is a byte word or longword?
A byte is eight bits, a word is 2 bytes (16 bits), a doubleword is 4 bytes (32 bits), and a quadword is 8 bytes (64 bits).
What is type in Delphi?
Description. The type keyword is a fundamental part of Delphi. Unlike other languages, it allows new categories (types) of variable and process to be created. These newly named categories can then be referenced just as if they were a part of the language.
How many bytes is a Halfword?
2
A halfword is 2 consecutive bytes. A fullword is 4 consecutive bytes. A doubleword is 8 consecutive bytes.
What is unsigned in C?
unsigned char is a character datatype where the variable consumes all the 8 bits of the memory and there is no sign bit (which is there in signed char). So it means that the range of unsigned char data type ranges from 0 to 255.
What is an int * in C?
int* means a pointer to a variable whose datatype is integer. sizeof(int*) returns the number of bytes used to store a pointer.
What is the longint type in Delphi?
The LongInt type is a 32 bit signed Integer. This size is fixed, and will not change in future releases of Delphi. It is currently the same size as the Integer type. To hold very large signed integers, use the Int64 type. Download this web site as a Windows program.
What is Delphi Longword and is it platform dependent?
Delphi LongWord is the underlying platform’s C++ unsigned long int. All four of these types are platform dependent. On all supported platforms at the time of writing, Integer and Cardinal are 32 bit types. The types are platform dependent, it so happens that on all supported platforms the types are the same size.
What is the difference between longint and cardinal and unsigned integer?
Integer is a 32-bit signed integer type – Longint is an alias for this type. Cardinal is a 32-bit unsigned integer type – LongWord and DWORD are aliases for this type.
What is the difference between Dword and longint?
On 64 bit *nix platforms, LongInt and LongWord are 64 bit types. On all other supported platforms, at the time of writing, the types are 32 bit types. The key point is that these types are all platform dependent. DWORD is a type alias used by the Windows API. Use it only when using that API. Should you use Integer or LongInt?
