A simple type is a single value which can be stored in an Identifier. Simple types are predefined by the compiler, but are not reserved words. While it is not recommended, they can be redefined.
Simple types predefined by the compiler are:
name | bytes | comment |
---|---|---|
boolean | 1 | |
cardinal | 4 | |
char | 1 (unless you use {$mode DelphiUnicode} or {$ModeSwitch UnicodeStrings}, then it will be 2) | most likely 1 |
int8 | 1 | by definition |
int16 | 2 | by definition |
int32 | 4 | by definition |
int64 | 8 | by definition |
integer | either 2 or 4, depends on compilation mode | |
shortint | 1 | <= integer |
smallint | 2 | <= integer |
longint | 4 | >= integer |
byte | 1 | by definition |
word | 2 | by definition |
dword | 4 | by definition |
qword | 8 | by definition |
pointer | depends on target cpu bitness: on 32-bit it is 4, on 64-bit it is 8 | |
single | ? | single precision float |
double | ? | double precision float |
extended | ? | extended precision float |
real | ? | |
currency | ? |
