| 1 | + | A shortint is a signed integer in the range of -128 to 127. The shortint is 8 bits long. | |
| 2 | + | ||
| 3 | + | The [[Byte]] type is 8 bits long, too. But the byte datatype is an unsigned type, meaning that it encodes numbers from 0 to 255. | |

| 11 | + | begin | |
| 12 | + | a_shortint := %11110001; // binary number | |
| 13 | + | a_byte := %11110001; | |
| 14 | + | s1 := IntToStr(a_shortint); // s1 = '-15' | |
| 15 | + | s2 := IntToStr(a_byte); // s2 = '241' | |
