If you compare the REAL_TO_INT with an M580 and Quantum, you will see some differences.
For example:
Quantum 2.5 = 2
M580 2.5 = 3
The M580 uses the method called "round to nearest, ties away from zero".
The Quantum uses the method called "round to nearest, ties to even" (as described in ControlExpert help).
The following table shows an example:
These two methods can be found in the IEEE 754 (IEC 559).
For example:
Quantum 2.5 = 2
M580 2.5 = 3
The M580 uses the method called "round to nearest, ties away from zero".
The Quantum uses the method called "round to nearest, ties to even" (as described in ControlExpert help).
The following table shows an example:
| Mode | 11.5 | 12.5 | -11.5 | -12.5 |
| to nearest, ties to even | 12 | 12 | -12 | -12 |
| to nearest, ties away from zero | 12 | 13 | -12 | -13 |
These two methods can be found in the IEEE 754 (IEC 559).
