An operand of data type SINT (Short INT) has a length of 8 bits and consists of two components: a sign and a numerical value in the two's complement. The signal states of bits 0 to 6 represent the number value. The signal state of bit 7 represents the sign. The sign may assume 0 for the positive, or 1 for the negative signal state.
An operand of data type SINT occupies one BYTE in the memory.
The following table shows the properties of data type SINT:
| Length (bits) | Format | Value range | Examples of value input |
|---|---|---|---|
| 8 | Signed integers (decimal system) | -128 to +127 |
The value range extends to a maximum of SINT#255 when using the type SINT#. This value is interpreted as an integer with -1. |
| 8 | Binary numbers (only positive) | 2#0 to 2#0111_1111 |
|
| 8 | Octal numbers (only positive) | 8#0 to 8#177 |
|
| 8 | Hexadecimal numbers (only positive) | 16#0 to 16#7F |
The value range extends to a maximum of SINT#16#FF when using the type SINT#. This value is interpreted as an integer with -1. |
