Title: UInt32
| Old | New | Line | |
|---|---|---|---|
| 1 | + | Back to [[Data type|data types]]. | |
| 2 | + | ||
| 3 | + | Range of values: 0 .. 4294967295 | |
| 4 | + | ||
| 5 | + | Memory requirement: 4 bytes or 32 bits | |
| 6 | + | ||
| 7 | + | A [[Data field|data field]] of data type **UInt32** can only take positive integer values. Assigning other values leads to compiler error messages when the program is compiled and the compilation process is aborted. That is, the executable program is not created. | |
| 8 | + | ||
| 9 | + | Definition of a data field of type UInt32: | |
| 10 | + | ||
| 11 | + | ``` pascal | |
| 12 | + | var | |
| 13 | + | ui32 : uint32; | |
| 14 | + | ``` | |
| 15 | + | ||
| 16 | + | Examples of assigning valid values: | |
| 17 | + | ||
| 18 | + | ``` pascal | |
| 19 | + | ui32 := 0; | |
| 20 | + | ui32 := 4294967295; | |
| 21 | + | ``` | |
| 22 | + | ||
| 23 | + | Examples of assigning invalid values: | |
| 24 | + | ||
| 25 | + | ``` pascal | |
| 26 | + | ui32 := '0'; | |
| 27 | + | ui32 := '4294967295'; | |
| 28 | + | ``` | |
| 29 | + | ||
| 30 | + | The difference between the two examples is that the upper example is the assignment of literals of the type [[Integer]], while the assignment of the lower example is literals of the type [[String]]. | |
