[R_I] Conversion real to integer value
Function block R_I converts a real input to the next integer value and issues it at the output.
R_I converts a real input to the next integer value and issues it at the output.
R_I converts the input [In] to the next integer value and issues it at the output [Out]. Rounding applies the following concept:
Positive input values:
- Round to the next higher integer value if value after comma ≥ 0.5.
- Round to the next lower integer value if value after comma <= 0.5.
Negative input values
- Round to the next higher integer value if value after comma ≤ 0.5.
- Round to the next lower integer value if value after comma > 0.5.
In | Out |
|---|---|

10.0 | 10 |
9.5 | 10 |
9.499 | 9 |
-10.0 | -10 |
- 9.501 | -10 |
- 9.4 | - 9 |

< -32 768 1 | -32 768 |
1 Inaccuracies in calculation within the framework of resolution for real values is ca. +/- 128.
If the input value [In] is above the highest possible integer value (32,767) or below the lowest possible integer value (-32,768), it can no longer be displayed as an integer value. For this reason, the highest possible or lowest possible integer value is output at [Out].
Resolution of real values (24 bit => 8 digits) is limited. Thus, values from 16 000 000 cannot be displayed accurately.
